White fused alumina is white and harder and more brittle than brown fused alumina micro powder. It features strong cutting force, steady chemical property and excellent insulation. Its knoop's hardness is 2200-2300kg/mm2.It can be shaped, non-shaped, normal bulk density and high bulk density. All products will be supplied according to customers different requirements.
Brown fused alumina is brown and features toughness and impact strength. It can bear high pressure. Its knoop hardness is 1800-2200kg/mm2.It`s suitable for making bonded and coated abrasive tools, wet or dry blasting, super precision grinding and polishing, making high quality refractory materials, grinding carbon steel, alloy, malleable cast iron, hard bronze and semi-conductor materials.
Use:
For coated abrasives-jis/p standard, for vitrified tools-fepa standard, for resin bonded wheels-fepa standard, for blasting, lapping, polishing fepa standard.
