William Rowlands tungsten powder is 99.9% pure. Tungsten is relatively inert, resisting attack from acids and alkalis, although it will react with fused, oxidising alkali media. Tungsten powder is compressed and sintered to produce cemented carbides.
Tungsten powders can be used to create strong and durable proprietary alloys and other finished products.
With around 60% tungsten carbide is the most frequently used tungsten compound and is usually employed in hard metals based on WC-Co, WC-mixed carbide- Co, WC-Co/Ni/Fe or in cements.
William Rowland is a UK and European distributor for Wolfram GmbH.
Average particle size:
Tungsten powder particle size ranges from 0.5 micron to 25 micron and tungsten carbide powder particle size is 0.7 micron - 20 micron.
Qualities:
Tungsten powder has the highest melting point and lowest vapour pressure of all metals; it is incredibly dense with low thermal expansion. Tungsten carbide (WC) features a unique combination of properties: extremely high hardness combined with very high modulus of elasticity, as well as high electrical and thermal conductivity.
Applications:
Tungsten powder is used as a raw material for tungsten carbide manufacture and as a raw material to produce sintered tungsten and tungsten alloys.
