High Density W Cu Alloy Copper Tungsten Bar
Product Brief Introduction
W Cu Alloy is a composite of tungsten and copper, with both tungsten low expansion characteristics, but also has copper of high thermal conductivity properties, and the tungsten and copper in the thermal expansion coefficient and thermal conductivity can be adjusted with the W-Cu composition, also the composite can be machined to various shape, these features make the application of this composite with great convenience.
Application
(1). W Cu Alloy is used when a product or part needs to have a high heat resistance, low thermal expansion and high electrical or thermal conductivity.
(2)/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 WCu alloy.
(3).The alloy is also made into sheet metal, tubing and plate metal.WCu alloy is used to make contacts for both high and low voltage electrical devices, and for high speed steel devices and switches.
(4).The Spark Erosion (EDM) process calls for copper tungsten.Usually this process is used with graphite, but tungsten has a high melting point.This allows the CuW electrodes to have a longer service life than the graphite electrodes.This is crucial when the electrodes have been processed with complex machining.Since the electrodes are susceptible to wear the electrodes provide more geometrical accuracy than the other electrodes.These properties also let the rods and tubes manufactured for spark erosion be made smaller in diameter and have a longer length since the material is less likely to chip and warp.
