BALN is a brown fused aluminum oxide obtained from the refuction of high quality bauxite in an electric arc furance . Due to its toughness, BALN is recommended for use in bonded abrasives(grinding wheel,cutoff wheel,points,etc...) , coated abrasives (paper & cloth),blasting abrasives, as well as refractory applications.
