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. |

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. |

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. |

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. |

Third lowest melt alloy of the "Silversmith Alloys". Good color match to silver. |

SILVALOY 0 is extremely fluid at brazing temperatures and will penetrate joints with very little clearance. 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. |

SILVALOY 5 has good flow and wetting properties on copper, brass, and bronze. 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. |

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. |

Of the phos-copper brazing filler metals, SILVALOY 15 has more ductility and better electrical conductivity than the lower silver content phos-coppers. 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. |

SILVALOY 2 is extremely fluid at brazing temperatures and will penetrate joint with very little clearance. 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. |
