Zirconia aluminium oxide is suitable for stainless steel, carbon steel, alloy steel, etc.
Zirconia aluminium oxide (ZA) is produced by fusing alumina and zirconia raw material in an electric arc furnace at high temperatures and then by quenching, crushing and sizing to the desired grain size. Especially suitable for stainless steel, carbon steel, alloy steel, etc.
ZA25 is mainly used for high-pressure snagging wheels and large organic grinding wheels.
ZA40 is used for both coated and bonded abrasives.
