Product Description of Brown Alumina Oxide
Medium-temp Calcined Brown Fused Alumina are calcined at a specific temperature according to the particle size, and then undergo subsequent processing. The organic matter present in the abrasives is vaporized, and the abrasives become pure in quality, with high cleanliness, good hydrophilicity, small expansion coefficient, and high toughness. , lower magnetic content and high strength, which can improve the grinding efficiency and precision of abrasive tools, and is more suitable for the production of high-end coated abrasives and bonded abrasives.
Application of Brown Alumina Oxide
Brown Fused Alumina Oxide is used for Sandblasting:
Blasting of glass, granite, marble, and ceramic, cleaning metal or metal finishing; de-burring; surface preparation prior to painting or bonding; rust or scale removal...
