What is tungsten copper alloy?
Tungsten Copper Alloy (Copper Tungsten, 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 microstructure is therefore rather a metal matrix composite than a true alloy. Copper tungsten alloy product is a sintered copper tungsten material, and always manufactured by powder metallurgy. It forms dense composite offering hardness, wear resistance and a high softening temperature of tungsten combined with the good electrical conductivity of copper
Tungsten copper alloy commonly contains 10 to 50 wt. % of copper, the remaining portion being substantially all tungsten. The typical properties of the alloy depend on its composition. Tungsten copper alloy with less wt.% of copper has higher density, higher hardness and higher resistivity. The typical density of CuW90 alloy, with 10% of copper, is 16.75g/cm3 and 11.85g/cm3 for CuW50 alloy. CuW90 has higher hardness and resistivity of 260 HB kgf/mm2 and 6.5 µΩ.cm than CuW50.
Tungsten copper alloy characteristics
Tungsten copper alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine. Parts are made from the WCu alloy by pressing the tungsten particles into a desired shape, sintering the compacted part, then infiltrating with molten copper. Sheets, rods and bars of the alloy are available as well.
