DURALUM® Redkote is a tough, cast fused aluminum oxide abrasive for use in resin bonded wheels when greater bond strength is required. A red iron oxide coating is ceramically bonded to the grain, using only lead free frits. An electronically controlled high temperature heat treatment assures a complete, void-free ceramic coating on the grain's surface. The fired ceramic surface bonds more intimately with phenolic resins. This better bond gives longer wheel life and improves grinding performance.
Duralum ® Redkote is used in a wide range of resin bonded applications, including:
- cut-off wheels
- steel-conditioning wheels
- cold pressed wheels
- depressed center wheels
- track-grinding wheels
