China refractory abrasive manufacturer WFA white fused alumina for sale
Henan Hongtai is one of the China main white fused alumina manufacturer located in Xinmi, Henan. White fused alumina is made from industrial alumina powder, smelted at a high temperature of more than 2250 degrees in an electric arc, and then cooled. It is crushed and shaped, iron is removed by magnetic separation, and sieved into a variety of particle sizes. White fused alumina has a dense texture, high hardness and sharp corners.
White fused alumina is suitable for manufacturing ceramics, resin-bonded abrasive tools, grinding, polishing, sandblasting, precision casting (corundum for precision casting), etc. It can also be used for manufacturing high-grade refractory materials. The code "WA" is consistent with international general standards and national standards.
White fused alumina is a kind of artificial abrasive, the content of aluminum oxide (Al2O3) is more than 99%, and contains a small amount of iron oxide, silicon oxide and other components, which is white.
White fused alumina particle size is produced according to international standards and national standards, and can be processed according to user requirements. The general particle size is F4~F220, and its chemical composition varies depending on the particle size. The outstanding feature is that the crystal size is small and impact resistant. If white fused alumina is processed and broken by a self-mill, the particles are mostly spherical particles, and the surface is dry and clean, and it is easy to bond with the binder.

White Fused Alumina has higher hardness and slight lower toughness comparing with brown fused alumina. White fused alumina is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emits, higher efficiency, acid and alkali resistance, good thermal stability. As abrasive material, White Fused Alumina is widely used for bonded and coated abrasive, polishing, precision casting and so on.

White Fused Alumina Production:
1. Add conductive material to the alumina powder, put it in the
furnace, dissolve it with electricity, spray water, cool, solidify,
and crush to form a block of white corundum with an aluminum oxide
content of more than 98%.
2. Crush and screen according to the size required by customers.
Most of the particles are spherical particles, commonly known as
"granular sand", and the general international particle size number
is F4-F220.
3. The screened fine powders are sieved through a hydraulic process, monitored in real time under a microscope, and dried to produce white corundum powder.
4. Packed in 25 kilograms per bag, and packed in tons of bags per ton, weighed with floor scales, and selected economical transportation methods according to customer needs.
White Fused Alumina Usage:
Scope of application:
White fused alumina abrasive is suitable for surface beautification
treatment of various high-end products, crafts or hardware. After
sandblasting, the surface is white without any impurities,
eliminating the trouble of cleaning.
Fine white corundum can be used as the first for polishing and grinding.
White fused alumina can also be used as various product additives. White fused alumina can be used as solid and coated abrasive tools, wet or dry or sprayed sand, suitable for ultra-precision grinding and polishing in crystal, electronic industry and making advanced refractory materials.
White fused alumina is suitable for processing hardened steel, alloy steel, high-speed steel, high-carbon steel and other materials with harder hardness and higher tensile strength.
White fused alumina is the main raw material for the production of medium and high grade indeterminate and shaped refractories. It is used for large ladle castables, medium and high grade iron trough castables, gunning materials, preforms and other amorphous refractories, corundum bricks, corundum and Various corundum products such as mullite corundum box body, corundum porous plug for refining, integral spray gun and composite nozzle, high-temperature industrial kiln lining material.
