Product Description

black fused alumina black corundum for abrasives 
 

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.

High content industry calcined black fused alumina Application

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
