High Density Tungsten Powder

Tungsten powder now is more and more popular for its high density for many fields as a safe, economical alternative to lead powder.

Its density is in 99% pure high density similar to that of lead powder but with better properties especially its environmental-friendly. Tungsten powder is over 30% heavier than the highest density lead powder and due to the powdery textures ability for compression, can add more weight in less volume. Tungsten powder qualities are fabricated by hydrogen reduction and are available in average particle sizes from 0.1 (100nm) to 100µm, which offers the possibility to produce that of any desired average particle size within various limits only by changes in reduction conditions.

The purity of the tungsten powder is of particular importance in all applications, typical upper limits of foreign element concentrations in µg/g are:

Co, Cu, Mg, Mn, Pb ≤ 2
Al, Fe, Ni, Si, Ca, Cr, Sn ≤10
Mo ≤ 20

The crucial physical properties are average particle size, particle size distribution, apparent, tap and compact or green density, specific surface area, degree of agglomeration and morphology. They are to a certain extent related to each other and can be influenced between limits by the oxide properties and the reduction conditions. Extremely coarse powder gained by screening to separate any finer particles has excellent flow characteristics and is used in plasma spraying.
