Wide Specification (WS) Tungsten Powder

Wide Spec (WS) tungsten powder is a lower grade of tungsten powder that is specifically developed for non-sintering applications where the high density of tungsten is desired yet extreme purity is not required. With a guaranteed minimum of 96% tungsten, you can have the high density of tungsten without the high price. Examples of applications include radiation shielding and plastic densification.

ANALYTICAL REPORTS

A Certificate of Analysis (COA) accompanies each shipment of tungsten carbide powder. BTI’s own Powder Metallurgy QC Laboratory prepares each COA to include the following:

Average Particle Size (Fisher Sub-Sieve ASTM B-330)
Apparent Density (Scott Volumeter ASTM B-329) ]
Particle Size Distribution (Photelometer ASTM B-430, Sedigraph, or Malvern Mastersizer)
Chemical Impurity Analysis
