Barmarc Grains Brown Aluminum Oxide for Metal Polishing

Product Description

Product Description

 

SEPPE Abrasive 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:

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.
