Tungsten Copper Grade

The grades of tungsten copper can be divided into the following four types：

70W30CU: It is formed by the process of static pressure moldings, high temperature sintering and copper infiltrated which combined with the advantages of excellent metal properties of the high pure tungsten powder, high purity copper powder plasticity and high conductivity.

75W25Cu: The tungsten copper electrode has the characteristics of high heat resistance, high thermal conductivity and low expansion, therefore, it is often used in resistance welding, electrical contacts and radiators. As a composite material of tungsten and copper, it has the excellent properties of copper and low thermal expansion.

80W20Cu: It is a tungsten copper grades CuW80 with a 15.58g/cm3 density, with 80% tungsten content and 98HRB hardness. It is widely used in substrates and chips which have the characteristics of silicon carbide, alumina and beryllium oxide and similar thermal expansion.

85W15Cu: This kind of tungsten copper has a great difference in physical properties of copper and tungsten, it can not be produced by powder alloy casting and casting. It is a kind of metal matrix composite made of tungsten and copper.
