Tungsten powder is the main raw material for processing powder metallurgy tungsten products and tungsten alloys. Pure tungsten powder can be made into processing materials such as wire, rod, tube and plate and products with certain shapes. Tungsten powder can be mixed with other metal powders to make various tungsten alloys, such as tungsten molybdenum alloy, tungsten rhenium alloy, tungsten copper alloy and high-density tungsten alloy. Another important application of tungsten powder is to make tungsten carbide powder, and then prepare cemented carbide tools, such as turning tools, milling cutters, drill bits and molds.

Product Specification:

Tungsten powder is classified into FW-1, FW-2 and FWP-1 according to its chemical composition and application. FW-1 is suitable for tungsten carbide powder raw materials, large slabs, processing materials, etc. FW-2 is suitable for contact alloys and high density shielding materials. FWP-l is suitable for plasma spray materials.
