Key Specifications/Special Features:
Brown fused alumina (brown aluminum oxide)Description:brown fused alumina (brown aluminum oxide) is electrically fused in an arc furnace from a mixture of bauxite at high temperatureHas brown color, high hardness and great toughnessAbrasive tools made of brown aluminum oxide are suitable for grinding carbon steel, normal alloy steel, malleable cast iron and hard bronzeUsed for refractory aluminum oxide lining mixture, pouring materials cast ableApplication of brown aluminum oxide:
- For resin bonded and vitrified abrasives: grinding wheels
- For coated abrasives: abrasive belts, sheets
- Wet and dry blasting media
- Grinding, lapping and polishing media
- Refractory aluminum oxide lining mixture, pouring materials cast able
- Brown fused alumina for abrasives can be divided into two kinds:
- For bonded abrasives: FT-A-01 (with medium density) and FT-A-02 (with high density)
- For coated abrasives: FT-A-P
- We can also produce medium (1050°C) and high (1350°C) temperaturecalcinedbrown Fused alumina and Iridium-plated BFA
