Brown Fused Alumina for Abrasives

详情

Brown Fused Alumina(also named Corundum, brown aluminium oxide) is an artificial corundum acquired by gradual smelting of bauxite in electric furnaces. The smelting process makes the material with higher content of Aluminium Oxide(Al2O3) and less content of free iron and silicon oxide. Content of Aluminum Oxide makes it have excellent hardness and high temperature resistance feature. It's an ideal material for abrasives,blasting and polishing,refractories products,casting and other heat resistant products.

After smelting,it's crushed and milled into different grits/sizes which are suitable for above purposes. **1mm,**3mm,**5mm,**8mm,**0mesh,**0mesh,**5mesh etc for refractories,castables and crucibles. FEPA F*-F**0 for bonded abrasives ceramic and vitrified, also blasting and polishing of different materials and industrial parts, P*-P**0 for coated abrasives like sandpaper,sand belts etc. Also finer FEPA grades like F**0,F**0,F**0,F**0,F***0 etc for cleaning and water jetting purposes on electronic parts,plastic and metal surfaces etc.

Brown Fused Alumina Typical Content:Al2O3: *5.5%, TiO2: 1.**2.5%, SiO2<1.7%,Fe2O3<0.*8%

Packing: 1M/T big bag or *5kgs bag, Pallet available
