Product Description

Fast Cutting Force Black Fused Alumina Synthetic Aluminum Oxide F24-F60 for Bonded Abrasives
1. Product Description of Black Fused Alumina Synthetic Aluminum Oxide

Black fused alumina is also a kind of corundum,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 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 and low cost.

3.  Product Features of Black Fused Alumina Synthetic Aluminum Oxide

  • Good Self-sharpness;
  • Moderate Hardness,not easy to burn the treatment surface;
  • Strong Cutting Force;
  • 40% Low price cost compared with the one of  brown fused alumina

4. Main Applications of Black Fused Alumina Synthetic Aluminum Oxide

Bonded abrasives :Resin cutting discs

Mixed 30-50% ordinary black aluminium oxide with brown aluminium oxide to make resin cutting discs ,which

will achieve better performaces: enhance the cutting discs’s sharpness and smooth finish , ease the surface

discoloration , and feel more stable when actual operation.

Most importantly,it will reduce the overall production cost because black aluminium oxide price is 40% cheaper

than the one of brown aluminium oxide.

 

Polishing stainless steel tableware

Compared with other higher hardness abrasives such as brown aluminium oxide ,black aluminium oxide has

the outstanding advantage of polishing stainless steel tableware,its moderate hardness & good self-sharpness

will generate little heat in the treatment surface,then hardly to burn the treatment,finally achieve uniform and

bright color.

 

Coated abrasives: sandpaper,sandbelts and flap wheels

The mixture of black and brown aluminium oxide can be made into sandpaper and then be converted into sand

belt and flap wheel for polish application.

 

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

Using black aluminium Oxide section sand as anti-slip aggregates not only meet the actual anti-slip demands

but also has higher price/performance ratio.

 

Polishing Waxes

Black aluminium oxide micropowder can also be made into a variety of polishing waxes for fine polishing

 

Refractory materials

It is also can be used to make unshaped refractory and the lining for steelmaking furnace.

 

Sandblasting media

Black aluminium oxide is also used for surface decontamination,pipeline cleaning,hull-rust

and Jean cloth sandblasting.
