High Hardness Brown Aluminum Oxide Artifical Corundum P60,P70,P90,P100 for Sand
Blets
1. Product Description of Brown Aluminum Oxide Artifical Corundum
Brown Aluminum Oxide belongs to the group of artifical corundum,its
contains at least 95% alumina, and
few Fe2O3,SiO2,TiO2 etc. Brown Aluminum Oxide is more durable than
the one of white fused alumina.
It has the characteristics of high hardness,high toughness,widely
used in varous industry to making bonded
abrasives,coated abrasives as well as blasting materials for
various surface cleaning etc.
2. Types of Brown Aluminum Oxide Artifical Corundum
Brown aluminum oxide F grit for bonded abrasives and P grit for
coated abrasives according to different usage;
Top Grade (Min95% Al2O3),off grade(Min90% Al2O3),second grade(Min80% Al2O3) according to different
alumina content.
Fixed Furnace and Tilting Furnace according to different furnace
types.
Ball milling, crusher, barmac brown aluminum oxide according to
different curshing methods.

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. Brown Aluminum Oxide Application in making coated abrasives
Brown Aluminum Oxide P60,P70,P90,P100 is widely used for making
coated abrasives such as
Jumbo rolls,sand paper to polishing the stainless still
tablewares,wood furniture, rattan, crafts etc.
In addition,Brown Aluminum Oxide is also used for the following
applications:
Bonded Abrasives such as resin cutting discs,grinding wheels for
cutting or grinding the the carbon steel,
oridiary alloy steel, calcinable cast iron, hard bronze, etc
Blasting media for oxide scale removal, rust
removal,etching,engraving,surface prepation, mold cleaning etc.
Refractiories for making high alumina brick, castables,furnace
lining etc.
Anti-skid material for highways,aircraft runway, parking area etc.
