White Fused Aluminum Oxide Powders (Microgrits)

Download: Technical Data Sheet | Safety Data Sheet (SDS)

Description:

White aluminum oxide is a high purity abrasive electrically fused from Bayer processed alumina. This material is classified to exacting standards for various applications where higher purity levels and reduced iron content are required.

Applications:

White aluminum oxide powders are used for micro blasting, precision lapping, fine grit grinding wheels, thermal coatings, polishing compounds, etc.
