Product Description of Semi-Friable Alumina Oxide
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.
Application of Semi-Friable Alumina Oxide
The bonded abrasives made by FA can be used for processing ordinary steel, bearing steel, all kinds of stainless steel, tool steel, low Cr/W/Mo/V/Co content special alloy steel, some cast ironsand all kinds of non-ferrous metals, such as, aluminium alloy containing Cu/Ni/Mg, copper containing S and Zn, magnesium alloy containing Al and Zn, etc.
