All called Fused Alumina, they have some different points,do you know it? Let us review it together!
1）Elements content.
Aluminum content is one of the vital differences between white, brown and black fused alumina
White Fused Alumina contains more than 99% aluminum.
Brown Fused Alumina contains 75-95% aluminum
Black Fused Alumina contains 45-75% aluminum.
2) Hardness.
White Fused Alumina： the highest hardness.
Brown Fused Alumina average hardness.
*The hardness of Black Fused Alumina：minimal among these three types of corundum.
3) Different colors.
Black Fused Alumina： metallic black color.
Brown Fused Alumina： brownish red.
White Fused Alumina： Mainly white color.
*4) Different usages.
White Fused Alumina used for the manufacturing of advanced refractory materials and precision polishing and grinding.
Brown Fused Alumina: used for sandblasting and rust removal.
Black Fused Alumina: cost effective and mainly used for rough polishing and non-slippery and wear resistant floor aggregates.
