Physical properties of tungsten copper alloy

Tungsten copper alloy combines the advantages of tungsten and copper, of which tungsten has a high melting point (tungsten melting point of 3410℃, copper melting point of 1080℃) and a high density (tungsten density of 19.25g/cm, copper density of 8.92/cm3); Excellent electrical and thermal conductivity of copper, tungsten copper alloy (composition of the general range of WCu7~WCu50) uniform microstructure, high temperature resistance, high strength, arc ablation resistance, high density; Moderate electrical and thermal conductivity, widely used in military high temperature resistant materials, high voltage switch electrical alloys, electromachining electrodes, microelectronics materials, as parts and components are widely used in aerospace, aviation, electronics, electricity, metallurgy, machinery, sports equipment and other industries.

CuW90 Tungsten Copper alloy Features

Due to the large proportion of tungsten content in CuW90 tungsten copper alloy, tungsten is hard but also easy to brittleness, which also creates good bending strength and hardness of tungsten copper, tungsten copper material has superior heat resistance and good thermal conductivity and conductivity, and at the same time has a comparable thermal expansion coefficient with silicon wafers and ceramic materials. And through certain conditions can control the relative content of tungsten copper to adjust its performance. Therefore, tungsten copper composites have become one of the ideal materials in the field of high temperature materials for electronic packaging.
