    1. Details

    ZIRCONIA FUSED ALUMINA

    CODE: BC-ZFA

      Zirconia Fused Alumina (ZA) is a kind of abrasive material whose crystal structure is made up of AL2O3 and ZrO2 together. It is made by Aluminum oxide and Zirconia which are electrically fused at high temperature.

      It is suitable for making all kinds of organic bond abrasive tools. The abrasive tools made by ZA are suitable for grinding and cutting all kinds of steel, especially for difficult grinding special steel and stainless steel. There are two kinds of ZA, one is ZA40, the other is ZA25.
