AZ40-F is true eutectic zirconia-aluminum oxide grain, produced by a unique process. Which involves the fusion of high grade alumina and zirconia sand at about 2000 ℃ temperature in an electric arc furnace. The molten products is cooled down rapidly on special cooling aggregates in order to create tiny crystal size and the extremely fine crystalline microstructure. This structure offers the high intrinsic grain strength and high resistance to dulling. Our AZ40-F is one of the most durable materials in the abrasive industry, outperforming other abrasives like brown fused aluminum oxide and silicon carbide. The demonstratedly spectacular cutting ability allows it for use in bonded abrasives and cut-off wheel applications like grinding of stainless steel.
