A typical grinding wheel specification consists of the grit type, the grit size, the hardness, the structure and the bond. A typical grinding wheel specification would be A60-I10-VS. ‘A’ is the grit type (aluminum oxide), ’60’ is the grit size, ‘I’ is the relative hardness, ’10’ is the structure, and ‘VS’ is the type bond.
Is brown aluminum oxide a possible substitute for high crystalline silica containing abrasive materials?
Yes. According to NIOSH, Brown Aluminum Oxide could be a viable substitute for consumers looking for safer alternative materials to high crystalline silica content abrasive products.
