Black fused alumina for bamboo and wood products polishing
Description
Black aluminum oxide use bauxite as its raw material, produced through the procedure of material sorting-electrolytic smelting-crushing-iron removal-magnetic separation-screening-physical and chemical inspection. It has 70-85% Al2O3 content, with suitable hardness and toughness, it can be used as a good media for bamboo and wood products polishing.
