  • ZIRCONIA RING – KIGAN

    As a result of our test, as a zirconia ring has better abrasion resistance than a SiC ring, the uppermost grade of new guide products released to the market soon was chosen as the zirconia ring. For reference, we are also using a method that increases surface hardness to 2,500 HV by coating TIN and TIC on the ceramic ring by using a vacuum deposition method.
