W50Cu50,W60Cu40 Tungsten Alloy Products WCu Alloy Round Plate
Tungsten Alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine.
Parts are made from the CuW alloy by pressing the tungsten particles into a desired shape,sinteringthe compacted part, then infiltrating with molten copper. Sheets, rods and bars of the alloy are available as well.

Features
Tungsten-copper alloy has a wide range of applications, most of which are used in aerospace, aviation, electronics, electric power, metallurgy, machinery, sports equipment and other industries. Secondly, it is also used to manufacture the contacts of high-voltage electrical switches and high-temperature components such as rocket nozzle throat liner and tail rudder, which are resistant to arc erosion, and also used as electrodes for electrical machining, high-temperature molds and other occasions requiring conductive and thermal conductivity and high-temperature use.
Applications
1. Arcing contacts and vaccum contacts in high and medium voltage breakers or vaccum interruptors
2. Electrodes in electric spark erosion cutting machines
3. Electrodes for resistance welding.
