* Artifical Corundum,We mainlu produce the High standard brown fused alumina, adopting the tilting furnace,crushed by the advanced vertical crush machine BMK, after the blowing&water washing, magnetic sorting and fine sieveing processes, our BFA products own higher density and purity than the common ones.

Basic minerals: Al2O3
Crystal Colour:Brown
Density:>3.9g/cm3
Mosh Hardness:9
Microhardness:HV1800-2200
Grinding ability:0.10

Very suitable for vitrified abasive tools producing, stable chemistry composition:
Al2O3>95%, SiO2<0.1%,Fe2O3<1%,TiO2 2.0-2.8%
The colour of the finished products is even,no cracks and rust.In a way, it reduces the percent defective.

Very suitable for sands blasting,our BFA Products have very high toughness, the crystal is irregular figure shapes.During the sandsblasting process,when one angle grinding, another two more angles will be out, can be used for many times,in a way, increased the working  efficiency.
