Brown Fused Aluminum Oxide Powders (Microgrits)
Download: Technical Data Sheet | Material Safety SheetDescription:
Aluminum Oxide is manufactured in an electric arc furnace that produces an extremely tough, high bulk density grain which is graded to exacting standards. By water classifying and chemically treating, our powders can be used in the most critical of applications.
Applications:
Aluminum Oxide powders are used for micro blasting, precision lapping, fine grit grinding wheels, break lining fillers, tumbling, polishing compounds, etc.
