Product Overview:
White Fused Alumina, commonly known as WFA, is a high-purity synthetic mineral produced through the fusion of controlled-quality pure grade Bayer Alumina in an electric arc furnace at temperatures greater than 2000°C and a slow solidification process. After the crude cools, it is further crushed and cleaned of magnetic impurities in high-intensity separators. It is then classified into narrow-size fractions to suit the end use. Dedicated lines produce products for different applications.
Advantages：
The white fused alumina produced by our company has the advantages of high purity, strong self-sharpening, strong grinding force, high efficiency, high temperature resistance and corrosion stability. Abrasive tools made of it have the advantages of sharp grinding, low heat generation rate, high grinding efficiency, and little adhesion during use.

Application：
White Fused Alumina is friable, making it perfect for use in products requiring a rapid, cool cutting action like Vitrified Bonded Abrasives. You’ll also find White Fused Alumina in high purity refractories used for coated abrasives, surface treatment and ceramic tiles. It’s even an ingredient found in anti-skid Paints, fluidized bed furnaces and skin.
It is resistant to alkali and has good corrosion resistance.
It can be used as a refractory material for high-temperature furnaces.
It has good thermal stability and can be used for a long time.
It is easy to store and transport.

The composition of white corundum is mainly industrial alumina powder, its main chemical composition is aluminium trioxide (Al2O3), with a content of more than 98%.
Support customisation, you can leave your demand on the left side form. We will contact you within 24 hours.
The hardness of white corundum is very high, the Mohs hardness is 9.0
Scratches appear in the polishing process because there are large grains in the abrasive product, resulting in a poor product appearance and poor cleanliness.
