Silver Brazing Alloys

SILVER BRAZING ALLOYS (CADMIUM FREE)

The silver brazing filler metals or silver brazing alloys, in the BAg classification are used for the joining of most ferrous and nonferrous metals, except aluminum and magnesium. At its liquidus temperature, the molten filler metal interacts with a thin layer of the base metal, cooling to form an exceptionally strong, sealed joint due to grain structure interaction. The silver brazed joint is composed of many different layers, each metallurgically linked to each other

Silver brazing alloys produce strong, sealed, leak-proof joints. Silver brazing alloys are available in numerous forms, including wire, rod, preformed shapes, paste, powder and strip.

 

SILVER-PHOS BRAZING ALLOYS

Silver-copper-phosphorus based brazing alloys are designed to braze copper to copper and copper to brass. These alloys are widely used in the refrigeration, air conditioning and plumbing industries primarily because of their resistance to corrosion. The phosphorus in these alloys act as a fluxing agent thus these alloys do not require a brazing flux when used to braze copper to copper. The silver in these alloys influence fluidity and improves the overall ductility of the brazing alloy. Silver-copper-phosphorus brazing alloys include a wide variety of compositions and melting temperature ranges and can be heated in many different ways. 

 

SILVER BRAZING ALLOYS (CADMIUM BEARING)

Cadmium is a known carcinogen and exposure to cadmium fumes may result in cancer and other hazardous side effects. Cadmium bearing alloys can be used for general purposes, joining large joint clearances and dissimilar combinations, joining ferrous and non-ferrous close fitting joints, and joining tungsten carbide tips and stainless steel. Typical applications include refrigeration and electrical components.
