Tungsten copper W85 block is composed of 85% W and 15% Cu, its density reaches(15.90g/cm3), hardness more than HB240, electric conductivity is 38%IACS, softening temperature is ≥900℃, thermal conductivity coefficient is between 180-200 (wm/k) and the coefficient of expansion is 7.0-7.5 (10-6k).
Tungsten copper block is prepared by powder metallurgy (PM), it has high strength and plasticity, even the temperature higher than 3000℃, tungsten copper still has uniform distribution because of copper evaporation.
Tungsten copper can be widely used in electrical material, which can be specifically divided into electrical contact and electrical machining.
| The standard length and width of tungsten copper block we are able to provide is less than 300mm, and the thickness is more than 0.1mm (±0.05mm), customized sizes and tolerances are also accepted.
