Semi-Friable Alumina

Home > Semi-Friable Alumina

Semi-Friable Alumina is a low titania containing brown corundum produced by controlled smelting of special grade Bauxite in an electric arc furnace above 2000 deg C. The lower titania gives an intermediate toughness between that of White and Brown Regular corundum and strict control of this parameter over a narrow band ensures consistent quality.

The cooled crude is further crushed, cleaned of magnetic impurities in high intensity magnetic separators and classified into narrow size fractions. The grains are further annealed at intermediate temperatures in a specially designed kiln to build predictable toughness characteristics.

In Bonded Abrasives, semi friable alumina can be used in depressed center wheels, cut off Wheels, in Surface and Cylindrical Grinding of heat sensitive metals, alloys etc. The wheels made of this material are made best use of where cool and fast cutting is required.

In Coated Abrasives, these grains are best suited for use in metal finishing and for sanding of wood, plastic coatings and paint.
