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.
zaf25 is the most dense and tough abrasive grains which produced by fused alumina and zircon at 1950 centigrade. with the alumina-zirconia eutectic crystalline structure, zaf 25 has extremely high wear resistance which impact the abrasive remarkable tool life zaf 25 mostly use in foundry-type grinding wheels and steel conditioning wheels.
