Zirconia fused alumina abrasive grit F30 for making heavy-duty wheels
Fused zirconia alumina is produced by putting rich aluminum, zirconium materials and additives in electric furnace, smelting with high temperature above 2000°C,cooling down with special technology, and compacting with Barmac plastic, which has the characteristics of tenacious texture, dense structure and high strength.
It is classified into ZA 25 and ZA 40 as the content of Zr02.
