Surface Ground Tungsten Copper Alloy Square Bars Thickness 2.0mm to 100mm W75Cu25

Tungsten copper alloy is the composite of Tungsten and Copper, which own the excellent performances of Tungsten and Copper, such as heat-resistant, ablate-resistant, high-intensity, excellent thermal and electrical conductivity. Tungsten copper alloy is easy to be machined. Tungsten copper alloy is used widely in such industries as engine, electrical power, electron, metallurgy, spaceflight and aviation. Using CIP formation, sintered tungsten skeleton and infiltrating copper (silver) technology, large size and special shape products of tungsten copper composites with 6-90 percent of copper are produced, such as electric contacts, electrode, refractory parts, heat sinks and parts of rocket, We can also produce tungsten copper alloy sheet material, tubing, plate and other small products by mould pressing, extrusion pressing and MIM.

Grade of Tungsten Copper Alloy Bar:
In reference to different chemical components and applying requirement, the grades of products are divided into four categories: W 50-90%, Cu 10-50%

Applicatioins of Tungsten Copper Bars:

Arcing contacts and vacuum contacts in high and medium voltage breakers or vacuum interrupt;

Electrodes in spark erosion cutting machines;

Heat sinks as passive cooling elements of electronic devices.

Advantages of Copper Tungsten Bars:

High arc resistance combined with good electrical conductivity
High thermal conductiveity
Low thermal expansion
Better heat resistant;
Better ablate-resistant;
Easyto be machined.
