Product Description

Hight hardness Black Fused Alumina grit For Abrasive media


Black Fused Aluminum Oxide grit for Metal surface cleaning abrasives mediaBlack Aluminum Oxide/Black fused alumina/Black Corundum is characterized by low Al2O3 and a certain amount of Fe2O3 (10% more or less) content, so Black corundum has characteristics of moderate hardness, high toughness, high temperature resistance, and stable thermal stability.what's more black fused alumina with the characteristics of strong cutting power, high toughness, high flexibility, good abrasion resistance and high working efficiency, It is the best product for grinding and polishing, sandblasting stainless steel products.



1.The processing of workpieces with black corundum is not only fast processing but also high quality.

2.The use of black corundum will not affect the color of the workpiece

3.The black alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.

1. Add appropriate amount of Black Fused Alumina, with black fused alumina, this resin cutting disc can improve the work life, and make the incision have higher quality, lowest cost.
2. The black fused alumina sand can be used as blasting media to process the surface if workpiece, cleaning impurity, pipeline cleaning, the body of vessel cleaning, Jean cloth sandblasting etc.
3. Black fused alumina coated grits can be made into all kinds of abrasive belt, flap disc etc. Used in a variety of workpiece polishing.
4. Black fused alumina grits can be made into fiber wheels, used in polishing the workpiece.
5. Black fused alumina fine powder can produce a variety of brake pads, which has moderate hardness, and beat dissipation characteristics.
6. Used of black fused alumina powder can be made into a variety of polishing wax, used for careful polishing of a variety of workpiece.
7. Black fused alumina is very good in polishing stainless steel tableware, hardly to burn the surface when lapping.
