Henan Superior Abrasives

More than 20 years of experience in the abrasive field, is Chinese leading supplier of silicon carbide and related products.

Black Silicon Carbide is mainly used for cutting and grinding brittle non-metallic materials, such as glass, ceramics, stone, refractory materials, grinding cast iron and some non-ferrous metal parts.

Green silicon carbide is made of petroleum coke and high-quality silica as the main raw materials, adding salt as an additive, and is smelted at high temperature in a resistance furnace.

White Fused Alumina has white color. The grinding tools made of this material are suitable for fine grinding of high carbon steel, high-speed steel and stainless steel, Abrasive powder of finer grit size, can also be used for precision casting and high-grade refractory.

Brown Fused Alumina, or BFA, is a material produced from high-quality bauxite and other raw materials. It is manufactured through a complex process of fusion in electric arc furnaces at high temperatures.
