Types SR and ST tungsten powders are the highest apparent density tungsten powder available. These powders are ideal for weight filler material and radiation shielding applications.
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 high density 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.
