Its broader melting range (250F) is helpful where clearances are not uniform. During melting, SILVALOY A54N passes from the solid state to a mushy or plastic state and progressively to a liquid. If heated slowly through this plastic state (1325-1575F) the liquid portion may flow from the solid portion. This causes a separation of the alloy into a low temperature melting (fluid) portion and a high temperature melting (solid) portion. This phenomenon is called liquation. The high temperature melting portion will melt only above the normal brazing temperature of SILVALOY A54N. For this reason, SILVALOY A54N should be heated rapidly through the melting range. Typical applications are the joining of ferrous, nonferrous and dissimilar metals and alloys.

Its slightly higher melt temperature provides improved mechanical strengths when exposed to elevated temperatures. Typical applications are the joining of ferrous, nonferrous and dissimilar metals and alloys with close joint clearances. It is used extensively in joining of copper, brass, nickel, silvers, and ferrous alloys. Good for refrigeration assemblies where higher temperatures can be employed.

Addition of nickel to the silver-copper zinc alloy imparts corrosion properties which retards joint or interface corrosion of the brazed assembly. SILVALOY A50N is a suitable replacement to the cadmium containing BAg-3 alloy SILVALOY 50N. Its low liquidus of 1305F reduces surface oxidation and sensitization to stainless steels. Typical applications are the joining of 300 series stainless steels in the food, medical, and dental fields. The nickel element in SILVALOY A50N also improves the bond strength when joining of tungsten carbide cutting tips. Used with 300 series stainless in Food, Medical, Dental fields. Good replacement of Silvaloy 50N in carbide brazing. 
BAg-27  SILVALOY 25  25.00  35  26.50  13.50              1125  605  1375  745  1575  Light Yellow  4.556  8.645  280  70  30  SILVALOY 25 is historically a modification of SILVALOY® 30 with a further reduction in silver content resulting in a higher melting point and a longer melting range (250ºF). It is similar to SILVALOY 30 in performance although it contains less silver. Its broader melting range is helpful where clearances are not uniform. During melting, SILVALOY 25 passes from the solid state to a mushy or plastic state and progressively to a liquid. If heated slowly through this plastic state (1125-1375F) the liquid portion may flow from the solid portion. This causes a separation of the alloy into a low temperature melting (fluid) portion and a high temperature melting (solid) portion. This phenomenon is called liquation. The high temperature melting portion will melt only above the liquidus temperature of SILVALOY 25. For this reason, SILVALOY 25 should be heated rapidly through the melting range. Typical applications are the joining of ferrous, nonferrous and dissimilar metals and alloys with close joint clearances. SILVALOY 25 is used for brazing steel, stainless steel, copper, copper alloys, nickel, nickel alloys or combinations of these metals. 
BAg-28  SILVALOY A40T  40.00  30  28        2        1200  650  1310  710  1550  Light Yellow  4.638  8.801  275  65  30  SILVALOY A40T is a good general purpose, low melting, cadmium-free alloy, often selected for its low temperature, wetting and good flow. SILVALOY A40T has a lower brazing temperature with a relatively narrower melting range than other cadmium-free classifications with similar silver content. It does not liquate excessively if heated slowly through its melting range. Typical applications are the joining of ferrous, nonferrous and dissimilar metals and alloys with close joint clearances. This alloy is particularly useful for joining steel, copper and copper alloys. It has proven most suitable for torch brazing with manual feeding into a joint where heating may not be consistent. It is also suitable for pre-placing as a ring or punching. 
BAg-2a  SILVALOY 30  30.00  27  23  20              1125  605  1310  710  1550  Light Yellow  4.618  8.763  275  65  30  SILVALOY 30 is historically a modification of SILVALOY® 35 with a further reduction in silver content resulting in a higher melting point and a longer melting range (185F). It is similar to SILVALOY 35 in performance although it contains less silver. Its broader melting range is helpful where clearances are not uniform. During melting, SILVALOY 30 passes from the solid state to a mushy or plastic state and progressively to a liquid. If heated slowly through this plastic state (1125-1310F) the liquid portion may flow from the solid portion. This causes a separation of the alloy into a low temperature melting (fluid) portion and a high temperature melting (solid) portion. This phenomenon is called liquation. The high temperature melting portion will melt only above the normal brazing temperature of SILVALOY 30. For this reason, SILVALOY 30 should be heated rapidly through the melting range. Less silver than Silvaloy 35 at the expense of increased metal temperature and range. Typical applications are the joining of ferrous, nonferrous and dissimilar metals and alloys with close joint clearances. SILVALOY 30 is mostly used for brazing steel, stainless steel, copper, copper alloys, nickel, nickel alloys or combinations of these metals. 
BAg-3  SILVALOY 50N  50.00  15.50  15.50  16    3          1170  630  1270  690  1500  Light Yellow  4.853  9.209  260  65  29  SILVALOY 50N is a modification of SILVALOY® 50. It was originally introduced because of somewhat better corrosion resistance than SILVALOY 50 for certain conditions, and is still used for such purposes. When melting, SILVALOY 50N passes from the solid state to a mushy or plastic range and progressively to a liquid. The largest portion of SILVALOY 50N melts in the upper section of its temperature range. Therefore, the alloy has a good body while in the plastic range and is suitable for building fillets or bridging large gaps. Late melting of the major portion of the alloy also helps minimize any separation of the solid and liquid portions by liquation during melting. It has proven successful on many marine applications and for dairy equipment which must withstand strong cleaning solutions. The 3% nickel content of this alloy also improves its wetting of stainless steel and tungsten, or molybdenum carbide tool tips. At the present time, largest use of this solder is for attaching carbide cutting tips to tool shanks. 
BAg-33  SILVALOY 25L  25.00  30  27.50  17.50              1125  605  1260  680  1400  Light Yellow  4.538  8.611  280  70  31  Similar to Silvaloy 25 but requires better heat control. Reduced melt range but more prone to oxidation.

This alloy, being free of Pb or Cd is preferred for long heating cycles and is suitable for use in controlled atmosphere brazing without flux. Typical applications are the joining of ferrous, nonferrous and dissimilar metals and alloys with close joint clearances. SILVALOY A38T is used for joining ferrous metals (stainless steel, Tungsten or molybdenum carbide), and nonferrous (copper, copper alloys, nickel, nickel alloys). The largest use of this alloy is for furnace brazing although it is also suitable for other brazing procedures. 
BAg-35  SILVALOY A35  35.00  32  33                1265  685  1390  755  1545  Light Yellow  4.568  8.668  280  70  31  SILVALOY A35 is a good general purpose alloy often used when cadmium must be avoided such as in the dairy and food industries. Typical applications are the joining of ferrous, non-ferrous and dissimilar metals and alloys with close joint clearances. It is mostly used for brazing in the electrical industry and for brazing brass parts such as ships, piping, band instruments, lamps, etc. Dissimilar metals brazing in refrigeration tubing. Moderate melt temperature for ferrous and non-ferrous alloys. 
BAg-36  SILVALOY A45T  45.00  27  25        3        1195  645  1251  675  1495  Pale Yellow  4.696  8.911  275  70  31  SILVALOY A45T is a free flowing, low melting and an excellent substitute to the cadmium-bearing filler metals with similar silver contents. SILVALOY A45T narrow melt range (75F) makes it suitable for manual or machine feeding into the braze joint. The alloy is best suited for narrow gap filling in the range of .001-.005 inches. Typical applications are the joining of ferrous, nonferrous and dissimilar metals and alloys with close joint clearances. SILVALOY A45T is particularly useful in joining steel, copper, copper alloys; and should be used in conjunction with Ultra Flux. The ability to join similar as well as dissimilar metals has allowed for numerous applications in the refrigeration and air conditioning fields. 
BAg-37  SILVALOY A25T  25.00  40  33        2        1270  690  1435  780  1625  Light Yellow  4.485  8.510  285  70  31  SILVALOY A25T is an economical filler metal for ferrous and nonferrous joints not requiring high ductility or impact strength. It is similar to SILVALOY® A40T, however flow is less active and temperature range and brazing temperatures are greater. This alloy is not ductile during cooling. After brazing, it must be allowed to cool without being subjected to mechanical or thermal stress. Least silver of this family. Moderate ductility limits joint design and application. 
BAg-4  SILVALOY A40N2  40.00  30  28      2          1240  670  1435  780  1650  Light Yellow  4.658  8.839  275  65  30  Good corrosion properties with stainless steels. Used in joining tungsten carbides. 
BAg-5  SILVALOY A45  45.00  30  25                1225  665  1370  745  1550  Yellow White  4.728  8.972  270  65  30  SILVALOY A45 is a good general purpose alloy often used when cadmium must be avoided such as in the dairy and food industries. Typical applications are the joining of ferrous, nonferrous and dissimilar metals. It is used for brazing in the electrical industry and for brazing brass parts such as ships, piping, band instruments and lamps. Excellent replacement to cadmium containing alloys. Broad application in furnace brazing. 
BAg-6  SILVALOY A50  50.00  34  16                1270  690  1425  775  1600  Yellow White  4.876  9.252  265  65  29  SILVALOY A50 is widely used for brazing in the electrical industry, as well as in the dairy and food industries where the use of cadmium-containing filler metals is prohibited. SILVALOY A50 has a broad melting range making it a good choice for filling wide joint clearances or forming large fillets. For best results, use with Ultra Flux. Widely used for electrical application and in joining dissimilar metals. 
BAg-7  SILVALOY A56T  56.00  22  17        5        1145  620  1205  650  1400  White  4.850  9.203  265  65  29  SILVALOY A56T has the lowest brazing temperature, best wetting, and best flow of all the cadmium-free alloys. It has a slight plastic range which may be noticed during melting on some applications. Its low zinc content minimizes problems due to longer heating cycles (as in furnace brazing) or due to excessive heating (as by less skilled operators). For this reason, it is often preferred over SILVALOY® 35, SILVALOY® 45, or SILVALOY® 50 for furnace brazing, or any brazing operation where the alloy is molten for an extended period of time. Typical applications are the joining of ferrous, nonferrous, and dissimilar metals, with close joint clearances. It is often selected for use on silver or stainless steel due to its excellent color match. SILVALOY A56T is often used on nickel, nickel alloys, or stainless steel because it does not cause stress cracking as readily as the other low melting brazing filler metals. The fact that SILVALOY A56T contains no cadmium has led to its use on food handling equipment where cadmium may be considered a hazard and its use is prohibited by law. Excellent replacement to cadmium containing alloys when low melt temperature is required. Good corrosion properties. Color match to stainless. 
BAg-8  SILVALOY B72  72.00  28                  1435  780  1435  780  1650  White  5.275  10.009  250  60  28  SILVALOY B72 is the eutectic composition of the silver-copper system. It is suitable for use in controlled atmosphere brazing without the use of any flux. When molten, SILVALOY B72 is very fluid and may flow out over the work surfaces during some furnace brazing applications. The wetting action on ferrous metals is limited, minimizing its use on carbon steel. Improved wetting is observed when furnace brazing of stainless steel with silver-copper filler metals. Typical applications are the joining of stainless steels, nonferrous (mostly copper and nickel alloys), and dissimilar metals. SILVALOY B72 should be used on setups with close joint clearances because it is a eutectic alloy, and very fluid. Good for atmosphere and vacuum furnace brazing of ferrous and non-ferrous. Used in critical electronic and aerospace brazements.

Best results are obtained with clearances of .001-.003". Melting of SILVALOY 0 is virtually complete at 1350F. Best results are obtained when brazing slightly above this temperature. The phosphorus content of SILVALOY 0 acts as a fluxing agent and no flux is necessary when brazing copper to copper joints. However, when used with a copper alloy or one of the other brazeable metals, a brazing flux must be used to promote wetting, bonding, and flow throughout the joint. The flow point of SILVALOY 0 is 1350F. SILVALOY 0 is used for the brazing of copper and copper alloys, brass and bronze. It is primarily used for the joining of copper-to-copper on vibration free joints. It is very effective for joining tight fitting copper pipe and tubing. SILVALOY 0 should not be used on ferrous metals or alloys containing more than 10% nickel due to the formation of brittle intermetallic phosphide compounds. Extensive flow, very fluid, recommended joint clearance.001" to .003" used with copper, brass and bronze base metal.

Its melting characteristics are such that on the low end of its brazing temperature range it has "sluggish" flow characteristics which enable it to fill gaps better, making it ideal for loose-fitting joints. On the other hand, when brazing at high end of its brazing temperature range, it is very fluid, making ideal for tight-fitting joints requiring deep penetration. The phosphorous content of SILVALOY 5 acts as a fluxing agent and no flux is necessary when brazing copper-to-copper joints. However, when used with one of the other brazeable metals, a brazing flux must be used to promote wetting, bonding, and flow throughout the joint. The flow point of SILVALOY 5 is 1325F. Used when gap clearance range is .003" to .006" ideal for larger copper pipe sizes. 
BCuP-4  SILVALOY 6F  6.00  86.75      7.25            1190  645  1325  720  1450  Light Copper  4.202  7.973  4500  1120  490  SILVALOY 6F has been universally accepted by repair and installation contractors because of its moderate flow with good filleting and gap filling characteristic when the joint fit up dimensions are less than ideal. The phosphorous content of SILVALOY 6F acts as a fluxing agent and no flux is necessary when brazing copper-to-copper joints. However, when used with one of the other brazeable metals, a brazing flux must be used to promote wetting, bonding, and flow throughout the joint. SILVALOY 6F is used for the brazing of copper and copper alloys, brass, and bronze. It should not be used on ferrous metals or alloys containing more than 10% nickel due to the formation of brittle intermetallic phosphide compounds.

It has good flow and wetting properties on copper, brass and bronze. The phosphorus content of SILVALOY 15 acts as a fluxing agent and no flux is necessary when brazing copper to copper joints. However, when used with a copper alloy or one of the other brazeable metals, a brazing flux must be used to promote wetting, bonding and flow throughout the joint. The flux used must be active within the required temperature range of SILVALOY 15 and active throughout the heating cycle. Of the phos-copper filler metals, SILVALOY 15 has the most "sluggish" flow characteristics. This enables it to fill gaps better. Melting of SILVALOY 15 is virtually complete at 1300F even though the liquidus is not yet reached. Best results are obtained when brazing slightly above this temperature. SILVALOY 15 is used for the brazing of copper and copper alloys, brass and bronze. It is very effective for joining pipe and tubing and is widely used for electrical work. SILVALOY 15 should not be used on ferrous metals or alloys containing more than 10% nickel due to the formation of brittle intermetallic phosphide compounds.

Best results are obtained with clearances of .001-.003". Melting of SILVALOY 2 is virtually complete at 1350. Best results are obtained when brazing slightly above this temperature. The phosphorous content of SILVALOY 2 acts as a fluxing agent and no flux is necessary when brazing copper to copper joints. However, when used with one of the other brazeable metals, a brazing flux must be used to promote wetting, bonding, and flow throughout the joint. Silver addition lowers solidus temperature, not as fluid as Silvaloy 0, gap clearance .001" to .003". SILVALOY 2 is used for the brazing of copper and copper alloys, brass and bronze. It is primarily used for the joining of copper-to-copper on vibration free joints. It is very effective for joining tight fitting copper pipe and tubing. SILVALOY 2 should not be used on ferrous metals or alloys containing more than 10% nickel due to the formation of brittle intermetallic phosphide compounds.
