Brown Fused Alumina is manufactrured mainly by high quality bauxite,with its performance dense texture,high hardness,it is suitable for the manufacture ceramic and resin abrasive tool with high consolidation,as well as used for grinding,polishing,sandblasting,precision casting and so on.Also used for making advanced refractories.
Brown Fused Alumina has high purity,good crystalline,good liquidity,low coefficient of linear expansion,etc,characteristics.Dozens of refractory manufactures have proved that the BFA has the advantage of non-powder,non-cracking and so on in the application processes.
