During the process of producing copper tungsten alloy, high purity tungsten will be sintered and infiltrated with the oxygen-free copper under an accurate consolidation. Because of this, there will be an excellent homogeneous microstructure for tungsten copper alloy.

A good combination of copper’s conductivity and tungsten’s high-temperature strength and arc-resistance will yield preeminent properties including arc ablation, strength, thermal conductivity, electrical conductivity. Tungsten copper alloy is perfectly suited to be applied as arc contacts, electrodes and high temperature furnace.
