Abrasive Meterial
White Fused Alumina
White Fused Alumina for Abrasives (SINO-WA-01) is a pure, clear Fused Alumina, which makes the whitest vitrified wheels possible with low soda and silica content. This is the most friable aluminum oxide. Due to its high purity and large crystal size, its crystals fracture comparatively swiftly and constantly cutting crystals to small pieces.

White Fused Alumina for Abrasives is used in the grinding of heat sensitive alloys. Taking advantage of its friability and cool cutting ability, it is widely used in precision grinding of high speed steels, segments and internal grinding wheels.
Available Sizes
F8-F220, F240-F120 or any other sizes by customer’s requirement.
Brown Fused Alumina
Brown Fused Alumina is made from high quality bauxite by fusing in an electric arc furnace at high temperature. It has good toughness and high hardness. It is suitable for manufacturing of Vitrified and Resin Bonded Abrasives, Coated Abrasives, for lapping, Polishing and Sandblasting.
The abrasive tools made of brown aluminum oxide are suitable for grinding carbon steel, normal alloy steel, malleable cast iron and hard bronze etc.
