Brown Fused Aluminum Oxide (BFA)
BFA is produced by fusion of bauxite in an electric arc furnace at high
temperatures.
BFA is of high hardness, toughness, self-sharpening, heat resistance and
chemical stability, etc.
BFA can be used in the manufacture of Bonded abrasives, Coated
Abrasives, Vitrified/Resin grinding tool, and refractory, etc.
angular / cubic
AF: has high hardness, strong self-sharpening, excellent heat resistance. It is suitable for resin-bonded cut off and grinding wheels, vitrified wheels, cutting cast iron, regular steel, carbon steel, and nonferrous metals such as hard bronze, etc.
F12 to F220; F230 to F1200, sized in accordance with the current GB/FEPA/JIS sieve standards.

angular
AP: has high toughness, strong cutting force and electrostatic adsorption force. It is suitable for Coated abrasives in metal working industry, such as sanding construction and tool steels, tool steel, cast steel, cast iron; also in non-ferrous metal like grinding aluminum, copper, hard wood, fiberboard, etc.
P16 to P220, P240 to P2500, sized in accordance with the current GB/FEPA/JIS sieve standards.

angular / cubic
AC: reddish brown color. It is heat treated in the calcinations temperature. It has higher purity, cleanliness, stronger hydrophilicity, smaller expansion coefficient, higher toughness, lower content of magnetic materials and higher strength. Suitable for high grade coated abrasives and bonded abrasives.
Coated Abrasives: P16 to P600
Bonded Abrasvies: F12 to F600

angular / cubic
AC: blue color. It is heat treated in high temperature calcination. It has higher strength, higher hydrophilic, can eliminate abnormal expansion during abrasive firing, can avoid the mech cracks / map cracks and rust spots of the fired abrasives. Suitable for top grade coated abrasives and bonded abrasives.
Coated Abrasives: P16 to P600
Bonded Abrasvies: F12 to F600

The Ceramic coated abrasive grains improve the bonding of the grains with the resin / the hydrophilicity of abrasive, heat resistance, self-sharpening, surface cleaniness and efficiency of grinding and cutting. It increase the life time and enhances the grinding properties.
Coated Abrasives: P16 to P220
Bonded Abrasvies: F12 to F220
Suitable for Sand Blasting, and lower quality Resin grinding / cutting wheels.
