Al2O3 95% P Grit Brown Fused Alumina High Hardness Brown Corundum
Al2O3 95% P Grit Brown Fused Alumina Corundum for Making Abrasive Paper/Belt
Brown Fused Alumina 95% Introduction
Brown Fused Alumina is called as the teeth of industry. It selected the bauxite,coke,iron scraps as raw materials,then fused in electric furnace under high temperature,then made into different sizes through one series process of crushing,screnning,magnetic separation,inspecting,packing.
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
