Tuncop 75W/25Cu Tungsten Copper
Tuncop 75W/25Cu
RWMA Class12
Tuncop is a copper alloy with tungsten.
Produced by powder metallurgy, this is a copper alloy containing 75% tungsten.
Tungsten has high resistance against arcs generated during welding.
The high electrical conductivity of copper allows it to be used as electrode.
