White Fused Alumina Characters

High Alumina

White Fused Alumina has a Aluminium Oixde(Al2O3) content of more than 99%. The high alumina content is ensured from its raw material which is calcined alumina.The high content of Al2O3 makes it perform well in fireproof and refractory applications.

Little Impurities

White Fused Alumina has very little impurities, usually less than 0.4% Na2O, less than 0.15 SiO2 and less than 0.15 Fe2O3. It is chemically stable and little impurities make it ideal for refractory uses.

High Hardness

The high content of Al2O3 (Aluminum Oxide) makes it to be with very high hardness (Mosh Hardness≥9) and It’s usually utilized for grinding ,cutting, lapping, sandblasting, polishing, surface preparing and also for coated abrasive application, including sandpaper and sand belt.It’s not easy to break and good for abrasives. In abrasives industries, it is used for cutting wheels, grinding wheels etc, also used for coated abrasives applications like sandpapers. It’s white color and little impurities also make it excellent grinding and sandblasting media for preparing and polishing surface of metal, ceramic products etc. WA fines is also an good material for polishing and water jetting in electronics industry.

Sharp Edges

White Fused Alumina is a crystal mineral with sharp edges and widely used in sandblasting,cutting and grinding abrasives.
