Refractory Grade Brown Fused Alumina 0 1/1 3/3 5mm 325mesh Powder Brown Aluminium Oxide Powder For Castable Materials

Product Overview

Description

 

 

 Brown Fused Alumina:

 

The brown aluminum oxide is made from bauxite, carbon materials, iron filings as raw material through melting in the electric furnace. It suitable for grinding high tensile metal, such as: a variety of common steel, malleable iron and hard bronze, etc., can also create advanced refractory.

 

 Application of brown fused alumina:

 

grinding media, sandblasting media; surface cleaning, grit blasting, lapping, polishing, grinding,

sandblasting, etching  : wet and dry blasting  : mineral skin abrasion materials

metal finishing & surface preparation  : refractors, ceramics, coatings " bonded & coated abrasives.
