Tuncop 75W/25Cu

Categories: Copper, Tungsten Copper
  • Description
  • APPLICATION AREAS
  • Technical Details
Description

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.

APPLICATION AREAS

APPLICATION AREAS

Butt welding and spot welding of stainless steels; as an electrode

with high resistance to abrasion during sinking erosion operations.
