Silicon Carbide, Brown Corundum, White Corundum, Emery Materials

Black silicon carbide is brittle and sharp, and has a certain electrical and thermal conductivity, microhardness 3100-3280 kg/mm2. Abrasives made of black silicon carbide are suitable for processing metal and non-metal materials with low tensile strength, such as gray cast iron, brass, aluminum, stone, leather and rubber. In addition, black silicon carbide can also be used in refractories, electronics industry.Green Silicon Carbide GCGreen silicon carbide has high purity, brittleness and microhardness of 3280-3400 kg/mm2. With green silicon carbide made of abrasive tools, suitable for processing high hardness, brittle materials, such as tungsten carbide, optical glass, mari and ceramics and other hard and brittle non-metallic materials, green silicon carbide can also be used to manufacture refractory materials, electric heating elements and electrical components productsBrown Fused Alumina ABrown fused alumina is the main raw material of bauxite, which is smelted at high temperature. It is brown, high hardness and toughness. The abrasive tool made of brown corundum is suitable for the grinding of carbon steel, malleable cast iron and hard bronze. In addition, brown corundum is also widely used in refractory chemical fillers, precision casting and anti-slip materials.White Fused Alumina WAWhite corundum is made by smelting aluminum oxide powder at high temperature. White corundum is white, hardness is slightly higher than brown iron, toughness is slightly lower. The abrasive tools made of white corundum are suitable for the grinding of high carbon steel, high speed steel and quenched steel. It can be used as grinding and polishing brush material. White corundum can also be used for precision casting sand, spraying materials, chemical catalyst carriers, special ceramics, refractory materials and so on.EmeryEmery, also known as garnet series of silicate minerals, after careful hydraulic screening, mechanical processing, screening and classification methods made of abrasive materials, mainly used for grinding glass products, industrial rust and water cutting(1) The silicon wafer optical lens, precision instruments, polishing glass glass ware, ceramic stone, leather, plastic, metal parts can improve the finish(2) can be sandblasted cutting, is the manufacture of grinding wheel, whetstone, emery cloth, sand must raw materials(3) Can be used to build highway pavement, airstrip, wear-resistant rubber, industrial floor. Anti-slip paint and other good wear-resistant materials(4) Can be used as chemical, petroleum, pharmaceutical, water treatment filtration medium and drilling mud weighting agent(5) The protection of electroplating and nuclear pollution has a good effect, and it is the sand for washing factory jeans sandblasting workshop. Water cutting industry with superior sand.Physical indicators of emery: density 3.96-4.10g/cm3, melting point 1180-1280℃, Mohs hardness 7.49-8.00, specifications: 8-220 mesh.Chemical composition; SiO2 35-40%, Al2O3 18-20%, FeO 25-37%, Fe203 0.9-1.0%, MnO 0.5-2.0%, MgO 0.2-1.4%, CaO 2.2-3.9%
