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 90% 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
PACKAGING
Available in 500 lb/250 kg drums or 50-100 lb/25-50 kg pails
NOTES
-
All powders are commercially uniform in purity.
-
Higher apparent densities available as per customer request.
-
Also available mesh sizes for screening are 270 & 325 mesh as per customer request.
