Our Quality Control Department establishes standards for all tungsten carbide grades. Control checks are performed at each operation. Chemical analysis and grain size are checked to assure that all products conform to standards. Test pieces are made to determine physical properties: hardness, transverse rupture strength and density. Fractured and polished surfaces are examined micrographically, and test results of each lot are recorded. Certifications of test results are available.
