Brown Fused Alumina is made by high quality bauxite as main material, fusing and
purifying in a pouring electric arc furnace at a temperature of over 2200, and made into
different grain sizes through crystal, choosing, crashing, magnetic, separating, screening,
washing etc. The various grit sizes may be used for all types of bonded abrasive and
general industrial applications. And it also can be used as refractory material.
