Tungsten Carbide Reclaimed Powder

Tungsten Carbide is often used to create hardmetals for cutting steel. Once mixed with cobalt, binder, tungsten carbide is pressed and sintered. Sintered tungsten carbide is one of the hardest substances known to man, and is used to cut steel, drill circuit boards and a multitude of other high tech applications in the automobile and aerospace industries, and beyond.

Tungsten Carbide Zinc Reclaimed:  All hard scraps containing Cobalt (Co).

Tungsten Carbide Reclaimed Powder is available in four different grades.  All grades are all manufactured by the Zinc process of hard scrap reclamation.  Uniform batches and exacting quality control enhances its desirability of the manufacturers of cemented carbide. 

All powder is commercially uniform in purity.  The Chemical and Physical Analyses are determined for each production lot of powder by using commercially accepted methods.  The results of all relevant tests are reported to the customer on a Certificate of Analysis.
