1）Element content.
Aluminum content is one of the vital differences between white, brown and black aluminum oxide
White Aluminum Oxide contains more than 99% aluminum.
Black Aluminum Oxide contains 45-75% aluminum.
Brown Aluminum Oxide contains 75-94% aluminum.
2) Hardness.
White Aluminum Oxide has the highest hardness.
Brown Aluminum Oxide has average hardness.
The hardness of black aluminum oxide considered to be minimal among these three types of corundum.
3) Different colors.
Black Aluminum Oxide has metallic black color.
Brown Aluminum Oxide is brownish red.
White Aluminum Oxide is transparent and has white color.
4) Different uses.
White Aluminum Oxide one is used for the manufacturing of advanced refractory materials and precision polishing and grinding.
Brown Aluminum Oxide is used for sandblasting and rust removal.
Black Aluminum Oxide is cost effective and mainly used for rough polishing and non-slippery and wear resistant floor aggregates.
