Tungsten Copper Alloy Uses

Tungsten copper alloy powder is used in injection molds for mold pressing parts as well as extrusion pressing. It is also used as a die lubricant in molds. The alloy is machined in a factory setting to make highly complex and intricate components such as microprocessors. It is also used to make parts of microwave communication systems and other electronic technologies.

Tungsten copper alloy is used when a product or part needs to have a high heat resistance, low thermal expansion and high electrical or thermal conductivity. Tungsten copper alloy is used to make engines and electrical devices. It is also used in the fields of aviation and spaceflight. Electrodes, refractory parts, heat sinks, rocket parts and electrical contacts are all made out of tungsten copper. The alloy is also made into sheet metal, tubing and plate metal. It is used to make contacts for both high and low voltage electrical devices, and for high speed steel devices and switches.

An electrode is a device that conducts electricity when it makes contact with a nonmetallic part of a circuit. Tungsten electrodes are used in arc welding with tungsten inert gas (TIG) or in plasma welding. The electrode can withstand high temperatures without melting. The alloy is used because it is resistant to erosion that can be caused by constant contact with the electrical arc that is used in tungsten welders. Tungsten electrodes are made out of a powder that is sintered and then shaped by a machine.
Semiconductors
A tungsten copper alloy that consists of 75 percent tungsten is used for substrates, chip carriers, flanges and frames of power in semiconducting devices. This type of alloy is used because its thermal expansion rate matches that of silicon, ceramics and gallium arsenide, all of which are used to make circuits for semiconductors.
