Product Description
Black Fused Alumina Chemcal Analysis
Black aluminum oxide fused corundum is also known as low aluminumcorundum. It is also a new type product of polishing material, and it isa dark gray crystal body made α-Al2O3 and ferropicotite as main ore inthe electric arc furnace by smelting the bauxite. It has characteristics ofmoderate hardness, high toughness, high temperature resistance, andstable thermal stability. It is mainly suitable for free grinding, such ascoarse grinding before electroplating products, mainly for polishing andsandblasting of stainless steel, fabricated metal products.

Application
1. Extremely hard, sharp, and durable abrasive2. Angular shape and fairly high bulk density will produce a matte surface finish3. Abrasive is generally reusable many times because of its hardness and durability4. Anchor pattern creation prior to coating or bonding5.Rust, scale, or other tough contaminant removal6. Application must tolerate some metal removal7. Used for grinding and lapping as well as abrasive blasting
