White Fused Alumina also called white aluminum oxide, white
corundum etc., is made from industrial alumina powder as raw
material, melted by the electrical arc after high temperature more
than 2000℃,then made into different grain size by crushing and
reshaping, magnetic separation, and screening. It has the
characteristics of dense texture, high hardness, high purity, good
self-sharpness & grinding ability, small heating power, high
efficiency, acid and alkali corrosion resistance, high temperature
resistance and good thermal stability.
Grain forms sharp corners, suitable for manufacturing vitrified
bonded, resin bonded abrasives and grinding, polishing,
sandblasting, precision casting, etc., can also be used for
manufacturing high-grade refractory materials. Code-named "WA"
