ANALYTICAL REPORTS
-- A Certificate of Analysis (COA) accompanies each shipment of tungsten carbide powder. We prepare 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
