Tungsten Powder
Tungsten powder is the primary 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 alloy, such as Tungsten Cobalt, Tungsten Rhenium, Tungsten Copper, and high-density Tungsten alloys.
Tungsten Powder Applications
Tungsten powder is widely used to produce weight fillers, radiation shielding fillers and induction accelerators, etc. The thin film surface of its polymer mixture is ideally suitable for radiation protection. The large particle size makes it an ideal heavy metal filler for injection-molding applications. The unique shape and the resulting high flowability of the particles make it suitable for the metal spray industry applications. 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.
