Zirconia Alumina 40

Zirconia Alumina is abrasive eutectic alloy of alumina and zirconia which produced by fused alumina and zircon at 2900 centigrade By specially controlling the fusion formula and cooling, it creates very fine micro crystal fracture properties which impact zirconia Alumina remarkable rapid stock removal rate and abrasive wear ratio. The mirco crystal structure support each working grain repeat quickly of the cutting edge by micro spalling. Avoid the cutting edge become dull could provide very low grinding resistance as well as very less thermal release. So that the fast and cool cutting action also protects the backing and adhesive system away from premature failure caused by heat embrittlementBy fusion inside different Titanium, we can obtain different tough-sharp balance.
