BROWN ALUMINUM OXIDE

BAO is a tough, medium density, virgin, fused brown aluminum oxide abrasive.

BAO is designed for pressure blasting of materials of almost every type, including glass, granite, marble and ceramic. It is also used for the preparation of surfaces prior to painting or bonding; as well as for light deburring, scale removal and a generation of matte finishes. BAO is closely sized, enabling operators to consistently duplicate finishes.


This product is produced to conform to C.I.D. -A-A-59316, General Electric Aircraft Engine Group D50TF5, and most Pratt and Whitney Aircraft PMC Specifications.
