Brown aluminium oxide is fused in an electrical furnace by high temperature. Its main raw materials are bauxite, anthracite. It dispalys brown.Its chemical composition contains Al2O3, a small amount of SiO2, TiO2, Fe2O3 and etc. The micro hardness is 1800 -2200 kg/mm2, The  toughness is higher than silicon carbide. Abrasive articles which mae of it are  suitable  for grinding metals of highten sile strength, such as steel, annealed malleable iron and hard high - class refractory products. The degree ofrefractory is up to 1850 C.

    Yichuan Sun Abrasives Factory: My factory locates near Yichuan county Luoyang city Henan province of China, The main imports and exports product : Brown Fused Alumina ( Abrasives or Corundum or Brown Aluminum Oxide): F-products  from size F12 to F220, Our product passes the water handles, it is very clean, W-products from F240 to F1500(W68 to W5) for the abrasives and 0 -1mm 1 -3mm 3 -5mm 5 -8mm 200mesh-320mesh for the refractoriness, we are looking forward to your inquiry and hope that we can have a good cooperation with each other.
