Brown 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.
Brown 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.
Properties of Brown Aluminum Oxide:
Extremely hard, sharp, and durable abrasive
Its angular shape and fairly high bulk density will produce a matte surface finish
Aluminum oxide is generally reusable many times because of its hardness and durability
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 applications
