Brown Aluminum Oxide (ALOX) – Abrasive

Brown Aluminum Oxide (ALOX) is suitable for wet or dry surface preparation, cleaning, deburring, and many other applications. Aluminum Oxide is available in grit sizes 16-240 in accordance with the current ANSI B74.12.

Brown Aluminum Oxide is a virgin grain, manufactured in an electric furnace that produces an extremely tough, long-lasting blasting grain which is graded to exacting standards. It may be repeatedly recirculated and is chemically stable and not affected by alkalies, acids or harmful atmospheres.

*Typical Chemical Analysis

Typical Sizing: is in accordance with ANSI B74.12 Table 2. For grit sizes 14-240.

The process of manufacturing fused aluminum oxide was developed at the end of the 19th century and involves smelting calcined bauxite and alumina in electric arc furnaces by electrothermal fusion at temperatures of around 2000°C. The resultant fused aluminum oxides are synthetic hard minerals based on α-aluminum oxide.

Fused aluminum oxides show a value of 9 on the Mohs scale of hardness close to diamond (Mohs 10), the hardest known substance. Besides their superior hardness, the characteristics of fused aluminum oxides include sharp-edged grains, great load bearing capacity, a high degree of shock resistance and thermal and chemical stability.

Our Brown fused Aluminum Oxide meets all major industry standards: (ANSI) B74.12 Table 3, MIL A21380 B, CID-AA-59316, CSS12 and GE D50TF5 CL D.
