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.

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.
