Tungsten Copper Tube
Tungsten copper tube is a composite material made by using the excellent metal properties of high-purity tungsten powder and the plasticity and high conductivity of high-purity copper powder through static pressing, high-temperature sintering, and copper infiltration. It has good arc breaking performance, good electrical and thermal conductivity, small thermal expansion, no softening at high temperature, high strength, high density, and high hardness.
High conductivity, high metal removal rate, so high productivity.
High hardness, long service life.
High density, high surface finish of processing mold.
The internal structure of tungsten copper tube is uniform.

Resistance welding electrode
Resistance welding electrode combines the advantages of tungsten and copper, with high temperature resistance, arc erosion resistance, high strength, high specific gravity, good electrical and thermal conductivity, easy cutting and processing, and sweating and cooling characteristics. Due to the high hardness, high melting point and anti-adhesion characteristics of tungsten, it is often used as projection welding and butt welding electrodes with certain wear resistance and high temperature resistance.
Electric spark electrode
When the mold made of tungsten steel and high-temperature resistant superhard alloy needs to be electro-eroded, ordinary electrodes have large loss and slow speed, while tungsten copper has high electro-corrosion speed, low loss rate, precise electrode shape, and excellent processing performance, which can ensure that the accuracy of the processed parts is greatly improved.
High-voltage discharge tube electrode
When the high-voltage vacuum discharge tube is working, the contact material will rise to several thousand degrees Celsius in a few tenths of a second, and the anti-ablation performance, high toughness, good electrical conductivity and thermal conductivity of tungsten copper provide the necessary conditions for the stable operation of the discharge tube.
Electronic packaging materials
Electronic packaging materials have both the low expansion characteristics of tungsten and the high thermal conductivity of copper. Their thermal expansion coefficient and electrical and thermal conductivity can be changed by adjusting the composition of the material, which provides convenience for the use of the material.
Large diameter tungsten copper tubes are mainly used for high temperature resistant parts of equipment, and small diameter tungsten copper tubes are mainly used for threaded electrode processing.
