How to Manufacture Tungsten Copper Alloy
How to Make Tungsten Copper AlloyTraditionally, tungsten copper alloy making commonly adopt copper permeability and liquid sintering technique. However as tungsten and copper indissolve each other and the sintering sex also poorer, it is difficult to implement fully sintering to optimize dense and form the uniform microstructure, and also hard to flexible adjustment of composition of copper tungsten. The followings are the commonly.
The merits of tungsten copper alloy made from this method are high density, good sintering performance, good thermal and electricity conductivity. However, this tungsten copper alloy needs further machining, which increase the machining cost, reduce the yield.
High temperature liquid sintering method
This method's advantage is that the processing is simple and easily control, while high sintering temperature, long sintering time and low sintering density which make the finished products can not meet the requirements of usage. In order to improve the density, repress, hot –press and hot forging after liquid sintering.
