Multiple specifications and compositions of tungsten copper plates produced by Tonghe. All copper tungsten plates, strips, and blocks are manufactured strictly in accordance with 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. Rigorous production control of tungsten copper alloys, strong research and development 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 composed of tungsten and copper, featuring tungsten's high-temperature resistance and copper's high electrical conductivity. Due to the significant difference in melting points between these two metals, traditional casting methods cannot be used for production. Instead, the copper tungsten alloy is produced through a mixed-powder, pressing, sintering, and infiltration process route.

Tungsten copper alloys, combining the high-temperature resistance, wear resistance of tungsten, and high conductivity of copper, offer excellent properties such as high hardness, high softening temperature, good conductivity, and ease of processing. These alloys find wide applications across various industries, with customers in all sectors.
