Black fused alumina is a dark gray crystal obtained from the fusion of high iron bauxite or high alumina bauxite in electric arc furnace.
Its main components are α- Al2O3 and hercynite. It features with moderate hardness, strong tenacity,good self-sharpening, low grinding heat and less prone to surface burning, making it an excellent abrasion-proof material.
Main Technical Data:
AL2O3 62%MIN
FE2O3 6-13%
SIO2 25%MAX
TIO2 2-4%
Black Fused Alumina Specifications:
Grit: F12-F400
Section Sand:3-5mm,1-3mm,0.4-1mm,0-1mm
Special specification can be customized.
Applications:
1.Resin Cutting Disc;
2. Polishing stainless steel tableware;
3.Wear-resistant anti slippery surface such as anti skid road,bridge,parking floor,airport runway etc.;
4.Sandblasting;
5. Abrasive belt and flap wheel;
6. Fiber wheel;
7.Polishing wax.
Black fused alumina is cheaper than the one of brown fused alumina,it will reduce the cost of use, and increase price/performance ratio.
