30# Brown Fused Alumina/BFA For Sand Blasting
Introduction of Brown corundum:
Brown corundum is made by electric arc furnace melting under high temperature with the raw material of bauxite, anthracite and scrap iron.
Brown corundum's color is brown. The main ingredient is Al2O3.With a refractoriness of 1850 ºC, brown aluminium oxide can be used in advanced refractory materials.
It has high toughness.Its micro hardness is 1800 - 2200kg/mm2.
Features of brown corundum:
The product of our factory has high purity, dense texture, high bulk density, self-sharpening, good toughness, ultra-low magnetic content characteristics, abrasive grinding it made a sharp, low fever, grinding ratio, and the use of less buildup; made of sintered abrasive with dark blue color after firing, can not afford to mesh cracks, no rust, suitable for the manufacture of ceramic, resin and high abrasive grinding, polishing, etc. .
