Code : WCu

Material Properties: Tuncop is a copper alloy with tungsten. Produced by powder metallurgy, this is a copper alloy containing 80% tungsten. Tungsten has high resistance against arcs generated during welding. The high electrical conductivity of copper allows it to be used as electrode.

Tuncop Areas of Application:

Butt welding and spot welding of stainless steels; as an electrode with high resistance to abrasion during sinking erosion operations.
