Leve1 brown fused alumina as the  polishing compound

 

1.About the brown fused alumina

 

 Properties: The bauxite, coke (anthracite) as main raw material, by smelting at high temperature in the EAF, the main chemical composition: Al203, Ti02 also small amounts of Si02 and Fe203. Characteristics: higher toughness than SiC, Microhardness 1800-2200kg/mm2, bulk density ≥ 3.85g/cm3, 

high temperature, high refractoriness1850oc.

 

2.Usage:

 made for abrasive, suitable for grinding high tensile strength metal, such as a variety of general-purpose steel, malleable iron and hard bronze, etc. it can also create high-level refractory material.
