Black Aluminum Oxide Artifical Corundum F24 F36 F46 F54 F80 for Resin Cutting Discs
1. Product Description of Black Aluminum Oxide Artifical Corundum
Black Aluminum Oxide is also called as synthetic aluminum oxide,black fused alumina.
It contains 60-80% Al2O3,which offers moderate hardness,it is also one kind of flexible abrasive,which is
widely mixed with other higher hardness or more durable abrasive to make various kind of abrasives such
as resin cutting discs.

3. Main Application of Black Aluminum Oxide Artifical Corundum
Black Aaluminum Oxide is widely used for make resin cutting dics,grinding discs,resin grinding wheel etc.
It is suggested to use 25% black aluminum oxide to partly replace brown fused alumina with the same grit
size or one more coarse grit size than the original one, it will achieved better grinding effect if adding 5%
black alumina F70&F80 to make the resin cutting discs more smooth.
In addition,Black fused alumina is also used in the following applications of
Coated Abrasives such as sand blets,sand paper,fiber wheels, flap wheels;
Polishing stainless steel tableware;
Sandblasting media for surface decontamination,pipeline cleaning,hull-rust and Jean cloth sandblasting;
Anti-skid wear resistant materials;
4. Why black aluminum oxide is suitable for making resin cutting discs?
Compared with the second brown alumina,black fused alumina is one abrasive produced specially,it has stable
chemical composition and stable crystallization which ensures stable performance and quality
Due to its moderate hardness and better slef-sharpness,there is little heat generated in the surface,so it will
achieve better cutting finish and little discoloration as well as higher cutting efficiency
The operator will feel more stable in cutting process
40% lower compared with the top grade brown alumina
