Brown Corundum, HS Code 28181010, CAS No. 1344-28-1, which are melting in arc furnace from three material alumina, carbon materials, and scrap iron, so the main chemical composition of brown corundum is Al2O3, its content is from 95.00% to 97.00%, the other contains a small amount of Fe, Si, Ti, brown corundum is the most basic of abrasive, grinding performance is good, because of its applicability is wide and its price is cheap, they are suitable for grinding the high tensile metals, such as all kinds of general steel, malleable cast iron, hard bronze, etc., also can make advanced refractories. Brown corundum they have the characteristics of high purity, good crystallization, strong liquidity, low linear expansion coefficient and corrosion resistance.

Brown Corundum Application:
- Used to produce high grade refractory, castable, refractory brick; Main size is 1-3, 3-5, 5-8mm.
- Sandblasting—–Features: Moderate hardness, high bulk density, without free silicon dioxide, good toughness, fine size and without ash.
- Application of sandblasting: stainless steel, iron workpiece, copper workpiece, glass product, plasthetics, aluminium extruded sections, Copper section, jean and special plus materials, plush processing and effect of pattern.
- Function: Remove surface stains, remove the welding slag and matt effect, remove oxide skin, surface strengthening, the role played by light.
- Sandblasting size: 46, 60, 80mesh(Big size could recycle more times. Or according to the customer’s request.)
- Grinding wheel—-When grinding high tensile strength materials, choice the good toughness
- brown fused alumina. When grinding low hardness with elongation of the material, choice brittle brown fused alumina.
- Coated abrasives and Bonded abrasives
- Floor sand
