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.
