Description

Black Fused Alumina Chemcal Analysis

Black aluminum oxide fused corundum is also known as low aluminum

corundum. It is also a new type product of polishing material, and it is

a dark gray crystal body made α-Al2O3 and ferropicotite as main ore in

the electric arc furnace by smelting the bauxite. It has characteristics of

moderate hardness, high toughness, high temperature resistance, and

stable thermal stability. It is mainly suitable for free grinding, such as

coarse grinding before electroplating products, mainly for polishing and

sandblasting of stainless steel, fabricated metal products.

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
