The high quality and high purity fine tungsten powders are typically greater than 99.95% tungsten purity with average particle sizes up to 10 microns. These powders are used in powder metallurgy applications such as electrical contacts, heavy metal alloys, electronic heat sinks, mining tools and fabricated tungsten rod/bar.
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 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.
