Product Description

Good Self-sharpness Synthetic Aluminum Oxide Black Fused Alumina F24 for Boned Abrasives

1. Product Description of Synthetic Aluminum Oxide Black Fused Alumina

Black fused alumina also belongs to the electric corundum group,it is made by high iron bauxite,high alumina

bauxite and iron oxide as main raw materials,then smelted in the electric arc furnace completely,then finally

 made into different grit size after different processes of cooling,crushing,screening etc.

It has the characteristics of moderate hardness,good self-sharpness,strong cutting force,not easy to burn the

treatment surface.

In addition,its price is 40 percent cheaper than the one of brown fused alumina, so it could partically replace

brown fused alumina in many applications such as boned abrasives.

3. Why Black Fused Alumina is Suitable for  making resin cutting discs?

Firstly,black fused alumina is one kind of corundum made by special process, having its own chemical composition

and crystallization condition compared with the second grade brown fused alumina, it has the more stable quality

to ensure the final products’ stability in performance;

 

Secondly,When mixing 30-50% ordinary black fused alumina with brown fused alumina to make resin cutting discs,

it will finally enhance the cutting discs’s sharpness and smooth finish , ease the surface discoloration, and feel more

stable when actual operation.

 

Thirdly,it will greatly reduce the overall production cost because black fused alumina price is 40% cheaper than the

one of brown fused alumina.

 

Fourthly,that application has been successfully used by Saint-gobain Group for over 10 years , now most famous

bonded abrasives plants is also widely using it.

 

In addition,Black fused alumina is also used in the following applications of
 

Coated abrasives: sandpaper,sandbelts and flap wheels;

 

Polishing stainless steel tableware;

 

Sandblasting media for surface decontamination,pipeline cleaning,hull-rust and Jean cloth

sandblasting;

 

Anti-slip aggregates in high traffic areas,aircraft runway, roads,bridge,parking floor etc.

 

Polishing wax;

 

Refractory materials.

 

4. How to use Black Fused Alumina to make resin cutting discs mixed with Brown Fused Alumina?

 

Generally speaking,when mixing black fused alumina with brown fused alumina to make resin cutting discs,

it is suggested to maintain or slightly reduce the original coarse grains of brown fused alumina , then use

30-50% black fused alumina to replace one or several fine grains of brown fused alumina according to the

original formula. It is also available to add about 5% finer grains(such as F60+70#, F70#) of Black Fused

Alumina when making large resin cutting discs,which will significantly improve the surface flatness and durability.

It is only a simple method for reference,people are able to find the right method according to their actual demands.
