White Fused Aluminum Oxide (Macrogrits) - Bonded Abrasives and General Industrial (Including Pressure Blasting)
Download: Technical Data Sheet | Material Safety SheetDescription:
White aluminum oxide is a high purity abrasive electrically fused from Bayer processed alumina. This product is ideal for applications that require minimal foreign contamination or higher friability than regular brown fused aluminum oxide.
Applications:
White Fused Aluminum Oxide Macrogrits are used for all kinds of bonded abrasives;
e.g. surface grinding, external and internal cylindrical grinding, creepfeed grinding of low or unalloyed steel, etc. General industrial applications include pressure blasting, microderm abrasion, anti-skid, and lapping.
