SILVER BRAZING ALLOYS – SPECIAL APPLICATIONS

The following are brazing alloys that, thanks to the addition of specific elements, or to their particular composition, have improved characteristics that make them suitable for specific applications or to operate in difficult conditions.
In particular, the addition of Nickel helps in joining difficult-to-braze materials (such as stainless steel, tool steel, tungsten carbide, nickel and nickel alloys, etc.) and improves corrosion resistance.
Manganese helps in brazing carbides.
Alloys without Copper are ammonia resistant.
Alloys without Zinc are suitable for brazing in oven and may be used to join stainless steels in wet conditions to avoid interfacial corrosion problems.
Alloys with Indium are suitable to join pieces that will undergo TiN coating.
