SEPPE Abrasives is an aluminum oxide brand specializing in brown fused aluminum oxide, otherwise known as fused alumina, through an electric arc furnace process.  Our brown fused aluminum oxide is made into many shapes and grit sizes ranging from macro grits to micro grits and powders. Brown fused aluminum oxide is a tough, hard material ( Mohs hardness 9 ) with high strength, excellent wear and corrosion resistance and good thermal conductivity. Fused alumina is widely used as a raw material in refractories, ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding and hundreds of other applications.

 

Brown Fused Alumina:

BFA is produced by a reduction fusion of high quality bauxites in electric arc furnaces. It is both a hard and tough material with high strength, making it an excellent abrasive grain for applications such as grinding wheels, sandpaper, blasting media, metal preparation, lapping, polishing, and grinding. Its thermal properties make it an excellent raw material for refractory applications.
 
Refractory material: Mainly used for abrasion and high temperature resistant, inoxidizable aggregate and filling of shaped and monolithic refractory in steel metallurgy, various industrial stoves, electric furnace etc.
