Specifications

Brown corundum is a high-quality abrasive grade bauxite as raw material, together with accessories, in the arc furnace by high temperature above 2250 °C refined steel. Its good self-sharpening, grinding and strong.

Corundum main chemical composition is AL2O3, its content 94.5% -97% in the other contains a small amount of Fe, Si, Ti and so on. The self-mill grinding plastic, magnetic separation to iron, sieve into a variety of size, its dense texture, hardness, the formation of spherical particles, for the manufacture of ceramics, resin and high-abrasive grinding, polishing, sand blasting, precision casting.

Grade corundum corundum main ingredient is alumina, aluminum content also graded to distinguish, the lower aluminum content will lower the hardness. Corundum color: Brown Fused Alumina is a brown color, in which three black corundum corundum is commonly known as the dark black color.
