WCu Welded Electrode

Tungsten-copper alloy is a pseudo-alloy with a microstructure consisting of a three-dimensional interwoven framework of tungsten and copper. This material combines the high melting point, high hardness, and high density of tungsten with the excellent thermal and electrical conductivity, machinability, and lubricity of copper. Its manufacturing processes mainly include isostatic pressing, high-temperature sintering of the tungsten framework, and copper infiltration using powder metallurgy methods. The tungsten-copper welded electrodes are composite materials made from tungsten and copper through powder metallurgy, possessing both high melting point, high hardness, and excellent electrical and thermal conductivity, and are widely used in resistance welding, electrical discharge machining, and other industrial fields.
