Granulated tungsten powders are extra large particle size tungsten powders made from the crushing of sintered tungsten metal. They are classified by coarse mesh sizes. Granulated tungsten powders have applications such as accelerator alloy powders.
ANALYTICAL REPORTS
A Certificate of Analysis (COA) accompanies each shipment of tungsten carbide powder. Our 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 Granulated tungsten 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.
