Product Description

Factory Supply Black Fused Alumina Oxide Abrasives Material

Black Fused Alumina, is a type of fused aluminum oxide, named by its black color. It's made of bauxite and Fe2O3 in tilting electric furnaces. It has lower content of Aluminum Oxide(Al2O3) and certain content of Fe2O3(about 10%).
It's mainly used for free abrasives and polishing on metal, stainless steel, wood, bamboo etc.And also abrasives grains for production of resin bonded abrasives tools and coated abrasives products. With its hardness and strength, it is also an good sandblasting media.

Application

1. Extremely hard, sharp, and durable abrasive

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

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

4. Anchor pattern creation prior to coating or bonding

5.Rust, scale, or other tough contaminant removal

6. Application must tolerate some metal removal

7. Used for grinding and lapping as well as abrasive blasting
