Introduction
White Fused Alumina (WFA) is made from Calcined Alumina and is a friable product. Like Brown Fused Alumina, WFA is used in the manufacturing of grinding wheels (both vitrified and resin bonded) and coated products. These grains are also used for shot blasting purpose and as polishing media and refractory grade WFA is used as raw material for high alumina refractories
Application
White fused alumina is mainly used for grinding high carbon steel, high-speed steel and chilled steel. It can also be used as lapping and polishing medium, precision founding sand and coating materials, catalyst carrier, special ceramics and super refractory material.

Function characteristics of white fused alumina sand: It will not affect the color of the workpiece; It can be used for sand blasting in the process of prohibiting iron powder residue; micro powder grade is very suitable for wet sand blasting and polishing; high processing speed and good quality; the content of iron oxide is very low, which is suitable for sand blasting operation in which iron slag is strictly prohibited; Remove impurities by pickling. White corundum abrasive treatment Many advantages of white fused alumina abrasive contribute to its important application in industry, but the waste of white corundum abrasive used in workpiece processing has become the main problem faced by enterprises. When white fused alumina abrasive is used, abrasive precipitation will occur. Of course, there will be other sundries on the workpiece. If the two are combined, the difficulty of cleaning will be further increased.
White fused alumina for sandblasting abrasive utilized by unique advanced technology. It is characterized by short grinding time, high efficiency and so on. In particular, its advantages such as high hardness, good chemical stability and unique self-sharpening , it becomes the first choice for the sandblasting technics, meanwhile, it is also the ideal material for sandblasting and derusting, workpiece cleaning, and polishing.
White fused aluminawhite, harder and more brittle than strong cutting force and steady chemical stability is good, has the very good insulation. White corundum with industrial alumina powder as raw material, regularly over 2000 degrees in the arc after cooling in high temperature melting, after smashing plastic, magnetic separation to iron, screen is divided into a variety of particle size, dense texture, high hardness, granular form sharp corners. Can be materials, etc. Suitable for machining hardened steel, alloy steel, high speed steel, high carbon steel hardness is harder, such as tensile strength of the larger materials. Can also be used to do touch media, insulator and precision casting sand, etc. Can also be applied to large steel castings, especially the type alloy casting, core sand, coating and investment casting shell making material, at the same time can be used as hardened steel, alloy steel, such as half fine grinding, fine whet.

Electrically fused from Bayer alumina ,white colour, its hardness is a little higher ,but toughness slightly lower than that of Aluminum .It is used for fabrication of bonded and coated abrasive products for the grinding of the steels with great hardness, such as high carbon steel ,allor steel, and high speed steel.Its non-abrasive uses are precision casting moulding sand ,spray coating material ,catalyat carrier ,high temperature ceramic ,and super refractory material,etc. Size Al2O3 Fe2O3 Na2O+K2O SiO2 Density Fire-Resistance Bulk Density Volume Density % % % % g/cm3 ¡ãC g/cm3 g/cm3 Grain 99 0.05 0.4 0.06 3.96 1850 1.5-1.95 3.6 Fine 98.5 0.07 0.4 0.08 3.94 1850 1.4-1.8 3.5 Micropowder 98 0.07 0.4 0.08 3.94 1850 1.4-1.8 3.5. 25 kg / bag/50kg/bag/ton bag.
brown fused alumina is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its high hardness,good toughness and shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as: carbon steel,general-purpose alloy steel,annealed malleable iron and hard broze,etc.It also can be used as refractory materials Applications: Brown fused alumina for coated and bonded abrasive tools Brown aluminum oxide for lapping and polishing processes Brown fused alumina for sandblasting Brown aluminum oxide for producing mold of precision casting Brow fused alumina as refractory materials
