Description of Tungsten Powder:
Tungsten powder is the main raw material for processing 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 carbide, such as tungsten cobalt alloy, tungsten rhenium alloy, tungsten copper alloy and high density tungsten alloy.
Applications of Tungsten Powder:
Tungsten powder is widely used in the production of weight fillers, radiation shielding fillers and induction accelerators, etc.. The thin film surface of its polymer mixture is ideally suitable for radiation protection. The la rge particle size makes it an ideal heavy metal filler for injection-molding applications. The unique shape and the resulted high flow ability of the particles make it suitable for applications in metal spray industry. 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.
Specifications of Tungsten Powder:
AEM provides tungsten metal powder by reducing tungsten oxides in a hydrogen atmosphere. We offer a highly diverse range of powder grades with average Fisher grain sizes from approx. 0.4 µm to >40 µm
