Product Description

Low Cost Black Aluminium Oxide Artifical Corundum F100 - F240 to Make Polishing Fiber Wheels
1. Product Description of Emery Black Aluminium Oxide

Black Aluminum Oxide is a black crystal with Al2O3 and iron spinel as the main ore phase, it selected the high

alumina bauxite, high iron bauxite or iron oxide scrap as the main materials, then melted in an electric arc furnace

under high temperature .


Its main chemical composition is aluminum oxide (Al2O3), ferric oxide (Fe2O3), and some silicon dioxide (SiO2),

titanium dioxide (TiO2) and other components.


Since black aluminum oxide is one wear-resistant product specially made by human control, it has the consistent

intrinsic composition and crystallization condition,which offers the stable performance compared with the second

grade brown aluminum oxide.

3. Main Features of Emery Black Aluminium Oxide :

  • Moderate Hardness
  • Good Self-sharpness
  • Low heat generation
  • not easy to burn the treatment surface
  • High Price/Performance Ratio

4. Main Application of Black Alumium Oxide to Make Fiber Wheels:

The fine grain of black aluminium oxide could be used for making fiber wheels,which is suitable for grinding and

polishing various workpieces.

Black aluminum oxide could also be mixed with brown aluminum oxide, or calcined brown aluminum oxide or

silicon carbide to make fiber wheels,that mixed fiber wheels has the dual function of grinding and polishing,also

higher price/performance ratio. The technical staff could find out the best solution and mixture ratio by experiments

according to their actual demands.


In addition,Black Aluminum Oxide  is also uesed in the following application:

Bonded Abrasives;

Coated Abrasives;

Blasting,Grinding,Polishing Media;

Anti-slip wear-resistant aggregates;


Fiber wheels;

Polishing waxes;
