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

Packing:In iron drums lined with double plastic bags of 50 or 100 kgs net each.
Note:Any particular requirements to the products can be discussed.
