Silver alloy brazing filler metal is a very widely used brazing filler metal. It is used to braze copper, steel, stainless steel, diamond, carbide alloys etc. Two main kinds are silver copper zinc alloy and silver copper phosphorous alloy. There are also silver copper, silver copper nickel alloys. It can be crafted to many forms, such as, rod, wire, ring, sheet, powder, paste, etc. This is a very widely used filler metal, especially in the industries of refrigerator, instruments, valve, glasses, tools, etc.
Silver alloy brazing filler metal usually is used together with silver brazing flux.
There are several types of silver brazing alloys varieties according to the materials, for example, Ag-Cu, Ag-Cu-Zn, Ag-Cu-Zn-Sn, Ag-Cu-P, Ag-Cu-Zn-Mn, and so on. Customers chose different type and compostion based on the different utility purposes.
