CADMIUM FREE SILVER BRAZING ALLOYS

CADMIUM FREE SILVER BRAZING ALLOYS

Country of Origin:
Taiwan

Detail Specifications / Descriptions

The cadmium free silver brazing alloys are used for soldering
with ferrous metals, copper and copper alloys, nickel and nickel alloys, and
special metal such as tungsten carbide. In part, a variety of composite alloys
have different characteristics which depend on the proportion of silver.
Generally, the alloys contain a high proportion of silver will lower the melting
temperature; they become whiter which unlike the brass color. The fluid property
of the alloy will also be improved during soldering process.


Tin is used in silver soldering alloys for the same purpose of
using cadmium. Mix of tin with silver, copper, and zinc alloy can lower the
melting point temperature, and improve the fluid characteristic when applied to
ferrous metals.


MAIN
USE : Ultra-hard alloy joint, cutting tools, cutters, tungsten steel, and high
speed steel etc., Cadmium is a poisonous metal. Therefore, we developed the
cadmium free silver brazing alloys which can be applied to food wares, medical
equipment, chemical equipment, etc
