BAg45CuZn Silver brazing materials BAg37CuZnSn BAg30CuZnSnNi Ag134 Application for Air conditioning valve
Silver brazing materials have excellent processability, good wetting and filling properties, low melting point, corrosion resistance, easy conductivity, high mechanical strength, and good plasticity. They are suitable for various brazing methods and can be used to brazing most black and non-ferrous metals such as stainless steel, carbon steel, hard alloys, copper, and copper alloys. Silver brazing materials can be further added to form multi-element alloy brazing materials by adding indium, tin, nickel, and other elements to meet various special performance requirements. Most brazing materials need to be used in conjunction with brazing agents to obtain stable and reliable joints during brazing.
