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.
