White Fused Alumina
Introduction of Andalusite:
White Fused Alumina is made from industrial alumina powder, which is made by smelting at high temperature above 2000 degrees in arc and cooling. It is crushed and shaped. Iron is removed by magnetic separation and sifted into various sizes.
With high quality and high density. It has high purity, good self-sharpness, acid and alkali corrosion resistance, high temperature resistance and good stability.
It can be widely used in sandblasting, grinding, polishing, cutting pieces, grinding wheels, consolidation abrasives, coated abrasives, precision casting, refractory bricks, castables, ramming materials, etc.
