Good Self-sharpness Aluminium Oxide Brown fused Alumina P12 - P220
for Coated Abrasives
1. Product Description of Brown Aluminium Oxide
Brown aluminium oxide is selected from high quality bauxite, coke,
iron scrap as raw material,then
melting in arc electric furnace under high temperature over 2,000
degrees, finally crushed and screened
into different grit size.

3. Main Products Features:
High hardness and toughness
Brown aluminium oxide contains more than 95% Al2O3,and its special
crystal form make it an hard
and tough material,which offers stronger cutting force ;
Good Self-sharpness
Its block and sharp grit shape offers new sharp edge in the cutting
process,it is suitable to cut the
alloy steel and stainless steel products.
4. Main Application of Brown Aluminium Oxide to make Coated
Abrasives
It is widely used in making coated abrasives such as sand belts,
flap discs, flap wheels etc.
In addition,it is also used for making boned abrasives, refractory
materials, blasting media, anti-skid
materials,brake pad etc.
