High Heat Brown Aluminum Oxide for Coated Abrasives

Heat treatments are often applied to Brown Aluminum Oxides. These may be either high heat or low heat; both enhance toughness, high heat more so than low heat. High heat treatment imparts a bluish color to the grain. Low heat is used to improve cleanliness and capillarity. Uses of heat-treated abrasives include grinding wheels, coated abrasives, and specialized industrial applications.

The abrasive grains for coated abrasives from YCDF are not simply processed by crushing, screening and magnetic separation, which are designed carefully, and through strict production process, such as shaping, water washing, air washing, chemical treatment, calcination, coating, recombination and grouping. The quality standard of grains, such as grains shape, toughness, bulk density, grains strength and hydrophilicity, is according to the customers' requirement and grinding application.
