AGSFA - Semi Friable Alumina

It is brown aluminium oxide containing low titanium di-oxide produced by controlled smelting of special grade bauxite in an electric arc furnace above 2000°C. the lower titanium gives an intermediate toughness between brown and white aluminium oxide to ensure consistent quality. Also the grains are further annealed at intermediate temperatures to get predictable toughness.
