JIS Standard Brown Fused Alumina 95% For Grinding Wheels Abrasives
JIS Standard Brown Fused Alumina 95% for Grinding Wheels Abrasives
Brown Fused Alumina Overview
Brown fused Alumina aluminum oxide is mainly used as a recyclable abrasive in blast cabinets and blast rooms. Because of its low iron content, alumina is often used in blasting operations where iron contamination on the non-ferrous metal substrate is not allowed. Aluminum oxide is a very hard and sharp abrasive that cleans rapidly. It leaves an anchor profile prior to coating and is suitable for removal of scale, rust and old coatings. Furthermore it is used for ceramic grinding wheels, refractory applications and polishing and grinding.
