金刚砂

Detail Product Description Brown Fused Alumina is made by high-quality bauxite as main material, fusing and purifying in a pouring electric arc furnace at a temperature of over 2200°C,and made into different grain size through crystal, choosing, crashing, magnetic, separating, screening, washing and acid cleaning, etc. It has the characteristics of high hardness, high toughness, resistance of high-temperature, anti-oxidation, corrosion resistance, etc. Corundum because of its high hardness, toughness is good, more used as a grinding material, which is one of the most basic abrasive. Applicable to carbon steal, malleable iron and hard bronze grinding, etc. In addition, in refractory materials, chemical additives, precision casting and anti-slip material also has wider application.
