We all know the white fused alumina is widely used in many industries. White fused alumina grit grain is produced according to National standard or other countries’ standard. And it can also produced according to customers’ requirements. The common grain is F4-F220, and the chemical specifications will be differently according to different grain size. The outstanding feature is the small crystal size and high impact resistance, if it is processed and broken by a self-grinding machine, the particles are mostly spherical particles with a dry and clean surface, which is easy to combine with the binder.

The white fused alumina takes the alumina power as the main material, add some materials like chromium oxide, etc. Produced by melting at a high temperature. Chrome corundum is pink, hardness is similar to white corundum, toughness is higher than white corundum. Abrasives made by white fused alumina have the good durability and high finish. Suitable for precision grinding of measuring tools, machine tool spindles, instrument parts, threaded workpieces and model grinding.

In the metallurgical industry, chromite is mainly used to produce ferrochrome and metallic chromium. Ferrochrome is used as a steel additive to produce a variety of high-strength, corrosion-resistant, wear-resistant, high-temperature, and oxidation-resistant special steels, such as stainless steel, acid-resistant steel, heat-resistant steel, ball bearing steel, spring steel, tool steel, etc. Metal chromium is mainly used to smelt special alloys with cobalt, tungsten and other elements. These special steels and special alloys are indispensable materials for the production of guns, missiles, rockets, naval vessels, etc. in the aviation, aerospace, automobile, shipbuilding, and defense industries. In refractory materials, chromite is used to make chrome bricks, chrome magnesia bricks and other special refractory materials.

In addition, white corundum is made from industrial alumina powder, smelted at a high temperature of more than 2000 degrees in an electric arc, and then cooled. It is crushed, shaped, magnetically separated to remove iron, and sieved into a variety of particle sizes. It is dense and has high hardness. The grains form sharp angles, which are suitable for manufacturing ceramics, resin-consolidated abrasive tools, polishing, sandblasting, silent casting, etc., and can also be used for manufacturing high-grade refractory materials.
