Tungsten Powder
Description
Tungsten (W) is relatively inert, resisting attack by oxygen, acids and alkalis, although it will react with fused, oxidizing alkali media. It has the highest melting point of all metals and, when pure, it can be worked with relative ease. Tungsten powder is mainly produced by the hydrogen reduction of high-purity tungsten oxides. Quality powder is an important part of tungsten alloy production. The properties of the powder affect the proceeding manufacturing process such as pressing and sintering, which affects the quality of the final tungsten alloy part.
As a worldwide supplier of tungsten products supplier, Alfa Chemistry supplies high-quality Tungsten Powder. Besides, at Alfa Chemistry we excel at taking tungsten powder and turning it into high quality tungsten alloy components.

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.
