Overview

 

AZ40-P is true eutectic zirconia-aluminum oxide grains, 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, which assures that each active grit particle retains its sharp cutting edge for an extended period. Thus an excellent cut rate at low pressure is allowed. Our AZ40-P is one of the most durable materials in the abrasive industry, outperforming other abrasives like brown fused aluminum oxide and silicon carbide. Because of its unique fracture properties, this abrasive material could maintain continous cuts on a microscopic scale as well as fast but cool cutting action, which protects the coated abrasive products.
