Brown Aluminum Oxide

Sandblasting material

Brown fused aluminum oxide is a synthetic, hard, and exceptionally durable abrasive material manufactured by electrically melting high-quality bauxite in an arc furnace. With a Mohs hardness of 9, sharp angular grains, and excellent toughness, it delivers high performance and long service life in grinding, blasting, polishing, and refractory applications across industrial environments.

Features

Mohs hardness rating of 9 for superior resistance to wear
Sharp, blocky/sawtooth grain structure for efficient cutting and material removal
High toughness and minimal particle shatter reduce dust generation
Chemical and thermal stability; resistant to acids, alkalis, oxidation
Produced via electric arc furnace fusion for consistent quality and purity

Applications

Bonded abrasives (grinding wheels, cutting discs)
Coated abrasives (sandpaper, abrasive belts)
Abrasive blasting media for surface preparation and rust removal
Refractory materials (bricks, castables in high-temperature environments)
Precision grinding, polishing, lapping of metals, ceramics, composites
