Product Description
Brown Aluminum Oxide Fused Alumina for Vitrified Bond, Resin Bond, Grinding Polishing Sandblasting Refractory
Brown fused alumina (A) is produced by fusion of bauxite in an electric arc furnace at high temperatures. The brownish coloured product shows high hardness as well as extreme toughness. The materials are used to grind metals of high-tensile strength such as steel, annealed malleable iron and hard bronze. It can also be used as high-class refractory.
Note: Special requirement on chemical composition can be satisfied through discussion.
Note: Special requirement on bulk density can be satisfied through discussion.
