Description: Tungsten copper alloy is also called copper tungsten alloy, consists of W and Cu, owns properties of heat resistant, high density, low thermal expansivity and high electrical conductivity, which has been widely used as electrode, contacts and heat sink materials.
Tungsten copper alloy (Copper Tungsten Alloy, CuW, or WCu) is a pseudo-alloy of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, high thermal and electrical conductivity, and easy to machine. Parts are made from the WCu alloy by pressing the tungsten particles into a desir
Tungsten copper parts provided by us are all with these properties. The electrical and thermal properties of the alloy vary with different proportions. Copper increases the thermal conductivity, which plays a huge part when being used in circuit breakers. Electrical resistivity with an increase in the percentage of tungsten present in the alloy, ranging from 3.16 at 55% tungsten to 6.1 when the alloy contains 90% tungsten. An increase in tungsten leads to an increase in ultimate tensile strength up until th
Part of the mixed powder sintering process copper infiltration method generally has the following two: Cu powder and 0.5% to 2.5% additives (typically nickel powder) - press molding - sintering - copper infiltration. The process is simple; this method is suitable for manufacturing Cu> 20% tungsten-copper composite. Various methods to the production of tungsten copper materials, copper distribution along the tungsten grain boundaries, the tungsten skeleton strength is not as good as the high-temperature sint
