China Zirconia Fused Alumina Aluminum Oxide

Quality Zirconia Fused Alumina Aluminum Oxide (ZAF25, ZAS25, ZA40-F, ZA40-P)
40% ZrO2 Fused Alumina Zirconia
ZA40 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. The materials are used for both coated and bonded abrasives.
