White Fused Alumina is fusedfrom high quality bayer aluminum in high temperature.
Its hardness is higher buttoughness lower compared with Brown Aluminum Oxide. It
is characterized by high purity,excellent self-sharpening, efficient grindingefficiency,
and low frictional heat. It canwithstand acid and alkali erosion, with high temperature
resistance and good thermostability.
