Factory supply 150# black fused alumina/black corundum abrasives
Product Description
Black fused alumina is also known as low aluminum corundum. It is also a new type product of polishing material, and it is a dark gray crystal body made α-Al2O3 and ferropicotite as main ore in the electric arc furnace by smelting the bauxite.With its hardness and strength,it is also a good sandblasting media.
Advantages
1.The processing of workpieces with black corundum is not only fast processing but also high quality.
2.The use of black corundum will not affect the color of the workpiece
3.The black alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.
