Good quality Tungsten Copper flat blanks W70Cu30
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
Spaceflight field
Tungsten copper alloy performance excellent as heat resistant, ablate resistant, high intensity, high density and self cooling, it is widely used in spaceflight field.
