Tungsten Powder

Tungsten Powder

Tungsten powder is the main raw material for processing tungsten powder and tungsten alloy. Pure tungsten powder can be made into wire, rod, tube, plate and other processing materials and certain shape products. Tungsten powder mixed with other metal powder, can be made into all kinds of tungsten alloy, such as tungsten alloy, tungsten rhenium alloy, tungsten copper alloy and high density tungsten alloy. Another important application of tungsten powder is made of tungsten carbide powder, and preparation of cemented carbide tools, such as turning, milling, drilling and molds etc..
