Product Description:
Brown Fused Aluminum Oxide is made by carefully selecting high grade brown fused alumina ingot, magnetic separation, sieving according to FEPA, ISO or Chinese GB particle size distribution standard and get different grit size.
Applications:
Different types of brown fused aluminum oxide abrasive grain are used for producing resin bonded, vitrified bonded, rubber bonded grinding wheels and abrasive tools or for producing coated abrasive sanding jumbo cloth rolls, sanding paper sheets. It’s also widely used for surface treatment, polishing lapping and sandblasting.
