Description
Tungsten Powder Product Overview
Tungsten (W) melts at about 3422°C, the highest of all metals, and has a very high density of about 19.3 g/cm³, close to that of gold. As a powder, it is gray and metallic and available in particle sizes from submicron to tens of micrometers.
The largest share of it is carburized into Tungsten Carbide for cemented carbide tools. Powder metallurgy producers also press and sinter it, with nickel and iron or copper binders, into tungsten heavy alloys for counterweights, vibration dampers and radiation shielding. Pure sintered tungsten forms electrodes, heating elements and lamp components.
Spherical tungsten powder is increasingly used in 3D printing and in thermal spray coatings. For related refractory materials, see Titanium Carbide, Vanadium Carbide and the binder metal Cobalt.

Frequently Asked Questions
Which particle sizes do you supply?
Grades from submicron to coarse and spherical powders for 3D printing are available. Please specify Fisher size or particle size distribution.
What is tungsten heavy alloy?
It is a sintered material of about 90–97% tungsten with nickel-iron or nickel-copper binders, used for its high density in counterweights and shielding.
How can I get a price and documents?
