Brown Aluminum Oxide
Brown Aluminum Oxide (BFA) is produced by the fusion of high-quality bauxite in an electric arc furnace at high temperatures. It offers high compression strength, high toughness, excellent self-sharpening, low thermal expansion, and outstanding hydrophilicity and cleanliness.

Overview
It is a clean, high-strength material that resists oxidation and corrosion, maintains chemical stability, and withstands extraordinarily high temperatures.
Calcined BFA
Heating to 1050°C greatly improves the purity, toughness, strength, and wear-resistance of abrasives. Primary application: vitrified grinding wheels.
Blue-Fired BFA
Firing at 1350°C turns grain color dark blue and achieves greater toughness and strength, much lower iron content, a very low coefficient of thermal expansion, and excellent hydrophilicity. Primary applications: coated abrasives and heavy-duty grinding wheels.
Ceramic-Coated BFA
Ceramic coating improves purity and hydrophilicity, reduces dust, and achieves grain surfaces with greater toughness, strength, roughness, and more uniform particle size.
