Product Description

Synthetic Aluminum Oxide Brown Fused Alumina F24 F30 F36 for Resin Cutting Discs


1. Product Description of Synthetic Aluminum Oxide Brown Fused Alumina

Synthetic Aluminum Oxide is also called as brown aluminum oxide,it is made by high-quality bauxite, coke,

iron scrap as main material, then fused and purified in an electric arc furnace at a temperature more than

2200° C,then made into different sizes through the special process of cooling, crushing, magnetic separation

and screening etc.

It has the characteristics of high hardness,high toughness,good-self sharpness,strong cutting force etc.


2. The types of Synthetic Aluminum Oxide Brown Fused Alumina


There is top grade (Min 95% Al2O3) brown aluminum oxide and  offgrade(Min 90%Al2O3) brown aluminum oxide,

second grade (Min 80% Al2O3)brown alumina according to the different alumina content.


Fixed furnace brown fused alumina and Tilting furnace brown fused alumina accoriding to

different type of electric furnace.


Barmac,Ball Milling,Roller Brown Fused Alumina according to different crushing methods.

4. Main Application of Synthetic Aluminum Oxide Brown Fused Alumina

Brown Aluminum Oxide F24#,F30#,F36# is the most popular grit size

It is widely used for making various kinds of resin cutting discs,which is suitable for cutting or grinding the

carbon steel, oridiary alloy steel, calcinable cast iron, hard bronze, etc


Brown Aluminum Oxide is also used for making ceramic grinding wheels for rough grinding, semi-finishing,

fine grinding,grooving,cutting purpose.


In addition, Brown Aluminium Oxide is also widely used for making coated abrasives,refractory materials, 

anti-skid materials, blasting media, brake pad etc.
