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.
