Flat Copper Tungsten Alloy Blanks W75Cu25 ≥ 885 Mpa Bending Strength

High Approval Tungsten Copper flat blanks W75Cu25

WCu 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. WCu alloy is easy to be machined. WCu 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 WCu 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 WCu alloy sheet material, tubing, plate and other small products by mould pressing, extrusion pressing and MIM.

Advantages

Higer thermal conductivity

Low thermal expansion

High arc resistance combined with good electrical conductivity

Applications

1.For the spark erosion of dies of cemented carbide and for making high speed steel and switches and contacts in high and low voltage electrical devices.

2.Resistance Welding
The high physical and mechanical properties, as well as the thermal and electrical conductivity, of refractory metal composites make tungsten copper alloy very suitable for die inserts and electrode facings, flash and butt welding dies, and hot upsetting. They can also solve heat balance problems.
