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 Tong He. All copper tungsten plates, bars, 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 surface spark discharge electrodes, resistance welding electrodes, and high-temperature-resistant components. We maintain strict production control over tungsten copper alloys, possess strong R&D capabilities, and adhere to a 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, combining the high-temperature resistance of tungsten with the high conductivity of copper. Due to the significant difference in melting points between these two metals, traditional melting 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 strengths of tungsten—high-temperature resistance and wear resistance—with those of copper—excellent conductivity. As a result, this composite material boasts high hardness, high softening temperature, good conductivity, and ease of processing. Tungsten copper finds broad applications across various industries, with clients in all sectors.
