Purity | 99.9% - 99.99% |
Tungsten copper (WCu) alloy is a composite of tungsten and copper, so both the thermal conductivity advantage of copper and the very low thermal expansion characteristic of tungsten can be utilized. By adjusting the content of tungsten, it is possible to have an appropriate thermal expansion to match with those of silicon (Si), aluminum oxide (A1203), beryllium oxide (BeO), etc. The copper content of commonly used alloys is 10% to 50%. Tungsten copper material has the properties of high density, sweat cooling, high-temperature strength, and erosion resistance.
