Al2O3 95% Titling Furnace Barmac Crushed Brown Corundum F30 for Bonded Abrasives
Brown Fused Alumina 95% Introduction
Brown fused alumina is fused and crystallized under high temperature from a mixture of calcined bauxite,coke(anthracite),scrap iron and other raw materials.
Brown Fused Alumina Characteristics
High hardness, high crystallinity, good linear flow performance, weak adherence, no explosion while using, no cracking, no pulverizing, abrasive product with dark blue color after burning, no net cracks, no rust.

Brown Fused Alumina Applications
Brown fused alumina is widely used as a raw material in many industries:
1. F-grit for bonded abrasives such as resin bonded grinding wheels, vitrified grinding wheels
2. P-grit for coated abrasives such as sandpaper, sanding belts
3. Blasting media, metal preparation
4. Laminates, coatings, lapping, polishing
5. Anti-slip applications like floor, ceramics, auto brake parts
