Product Description

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.
