Product Introduction

Tungsten Copper Sheet is a refractory metal alloy of tungsten and copper.It is made of copper powder and tungsten powder.It combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine.Copper Tungsten sheet is typically supplied to meet the standard of ASTM-B-702 and RWMA 12,RWMA 11.As a global leading supplier of copper tungsten sheet.We manufacture various sizes copper tungsten sheet,plate,rod,bar.

By selecting high purity tungsten powder and oxygen-free copper, all of our tungsten coppers are produced by sintering and infiltrating process.

The composition of tungsten and copper are well-proportioned and accurate percentaged;

Tungsten coppers are precisely machined with high thermo stability, high arc resistance and high strength;

Copper tungstgen has high electrical conductivity and thermal conductivity;

Tungsten Copper Sheet application and performance:
1. Arcing contacts and vaccum contacts in high and medium voltage breakers or vaccum interruptors;
2. Electrodes in electric spark erosion cutting machines;
3. Electrodes for resistance welding;used where the combination of high heat resistance, high electrical
4. Some of the applications are in electric resistance welding, as electrical contacts, and as heat sinks.
5. As contact material the alloy is resistant to erosion by electric arc. WCu alloys are also used in electrodes for electrical discharge machining and electrochemical machining.
