Surface Preparation Brown Aluminum Oxide Grit High Compression Strength Blasting Media
High Compression Strength Brown Aluminum oxide Fused Alumina for surface Preparation
1. Product Description of Brown Aluminium Oxide Fused Alumina
Brown Aluminum Oxide is a hard, tough, long-lasting material. It is called as the teeth of industry,which is
widely used in bonded abrasives,coated abrasives,blasting media,refractory,anti-skid materials etc. Its wide
application make it to be the teeth of industry.
Brown Aluminum Oxide is divided into different quality level according to its alumina content:
95% AL2O3,called Top Quality Brown Aluminium Oxide
80% AL2O3,named as The second grade Brown Aluminum oxide.
