Product description
Parameters
Tungsten copper (silver) composite
Tungsten-copper alloy combines some advantages of tungsten and copper, high temperature resistance, arc ablation resistance, high strength, large specific gravity, good thermal conductivity to point, small thermal expansion, easy cutting, and sweating and cooling. Widely used in machinery, power, electronics, metallurgy, aerospace and other industries. Tungsten copper products contain 7-50% by weight of copper
                 
Product Standards:GB/T 8320-2003orASTM B 702-93(Reapproved2004)
use:
Arc contacts and vacuum contacts for high and medium voltage switches or circuit breakers.
Electrode for machining
Radiator parts for electronic equipment
