Product Description

          24# Sand Blasting Grit Brown Aluminium Oxide 95% Al2O3

 

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.It is one popular blasting media in many applications, also widely used as raw material to make resin bonded abrasives and coated abrasives.
