Aluminum Oxide

Brown Aluminum Oxide

RockRidge Aluminum Oxide is manufactured in an electric arc furnace that produces an extremely tough, long-lasting grain which is graded to micro or macro grit exacting standards. Aluminum Oxide is an abrasives that can be repeatedly circulated.

Aluminum Oxide is suitable for wet or dry surface preparation, cleaning, deburring, and cutting of various metals, ceramics, glass, wood, rubber, plastic, stone, and composite materials. 

RockRidge Aluminum Oxide comes in either Brown-Fused or White-Fused. Brown-Fused Aluminum Oxide is a standard blasting abrasive while White-Fused Aluminum Oxide is a high-purity abrasive for when the application requires minimal foreign contamination or higher friability. 

Qualities of Aluminum Oxide:

  • Extremely hard, sharp, and durable abrasive

  • Angular shape and fairly high bulk density will produce a matte surface finish

  • Abrasive is generally reusable many times because of its hardness and durability

  • Anchor pattern creation prior to coating or bonding

  • Rust, scale, or other tough contaminant removal

  • Application must tolerate some metal removal

  • Used for grinding and lapping as well as abrasive blasting

  • Is a good choice for etching

Specific Qualities of White-Fused Aluminum Oxide:

  • Tough cleaning and surface etching applications that have a very low tolerance for iron residue

  • Extremely hard, sharp abrasive

  • Similar to brown aluminum oxide but manufactured for an extremely low iron content

  • More friable than brown aluminum oxide
