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 components of high temperature furnace.

We are capable of producing copper tungsten plates and sheets with a range of thickness from 12mm to less than 0.5mm. We also offer copper tungsten rods with diameters ranging from 0.029″ to 5.0” or more.
