Tonghe Copper Tungsten is widely used in industrial fields for EDM electrodes, resistance welding electrodes, and high-temperature components.

A variety of tungsten copper plates with different specifications and contents produced by Tonghe. All copper tungsten plates, strips, and blocks are manufactured strictly in accordance with the national standard GB/T8320. They feature high density, high conductivity, high hardness, and are used as mirror spark discharge electrodes, resistance welding electrodes, and high-temperature-resistant components. Rigorous production control of tungsten copper alloys, strong R&D capabilities, and professional after-sales service philosophy. Our tungsten copper alloy products are recognized by a wide range of customers in the market.

Tungsten copper alloy is a two-phase pseudo-alloy of tungsten and copper, featuring tungsten's high-temperature resistance and copper's high conductivity. Due to the significant difference in melting points between these two metals, traditional casting methods cannot be used for production. The copper tungsten alloy is produced through a mixed-powder, pressing, sintering, and infiltration process route.

Tungsten copper alloys combine the benefits of tungsten's high temperature resistance and wear resistance with copper's excellent conductivity, resulting in a composite material with high hardness, high softening temperature, good conductivity, and ease of processing. Tungsten copper finds wide applications across various industries, and we have clients in all of them.
