          Tungaloy ceramics consist of high purity fine powder Oxides,
          Nitrides and Carbides. The fine and dense compacting ensures
          superior wear resistance, adhesion resistance, oxidation
          resistance and heat resistance.
          These grades enable high speed finish to light machining, offering
          high accuracy and high quality surface finishes. Ceramic grades
          are classified into alumina base and silicon nitride based groups.
          These can be selected according to the application.
