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.
