Polishing abrasive powder

Properties: 

The bauxite, coke (anthracite) as main raw material, by smelting at high temperature in the EAF, the main chemical composition: Al²0³, Ti 0² also small amounts of Si0² and Fe²0³. Characteristics: higher toughness than SiC, Micro hardness 1800-2200 kg/mm², bulk density ≥ 3.85 / cm³, high temperature, high refractoriness 1850°C.

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.
