Duralum ® GW is a medium titania, blocky shape and medium density fused brown aluminum oxide abrasive.
Duralum ® GW is used in bonded abrasive products where a tough, strong, aluminum oxide is required.
DURALUMR GW/VIT is a specially treated, medium titania, blocky shape, medium density, fused brown aluminum oxide abrasive for use in vitrified bonded abrasive products where a tough, strong, aluminum oxide is required.
DURALUMR GW/VIT is manufactured specifically for use in both high temperature and low temperature vitrified grinding wheels. It is produced in a complete range of grit sizes.
Duralum ® HBD is a medium titania, blocky shaped, high density, fused brown aluminum oxide abrasive for use in bonded abrasive products where a very tough, mulled, aluminum oxide is required.
Duralum ® HBD is extensively used in heavy-duty grinding, double disc grinding and cylindrical grinding. It is suitable for both resinoid and vitrified wheels.
Duralum ® HRG is a medium crystal size fused brown aluminum oxide, specially heat-treated under carefully controlled conditions of time, temperature, and atmosphere. Duralum® HRG is an annealed abrasive due to the crystal realignment that occurs during its controlled calcining and cooling. A tough and strong abrasive, Duralum® HRG grinds with remarkable consistency and produces favorable grinding ratios characterized by rapid stock removal combined with minimal abrasive wear.
Duralum ® HRG is widely used in such diverse applications such as portable wheels, steel conditioning wheels, and cut-off wheels.
A medium titania, elongated shape, low density, fused brown aluminum oxide abrasive for use in bonded abrasive products where a tough, strong aluminum oxide is required but with cooler grinding characteristics.
Duralum ® LBD is an angular grain with very sharp edges for use in precision vitrified or organic grinding wheels where more friability is desired to achieve a faster, cooler cut.
Duralum ® LT is a true, semi-friable, fused, light brown aluminum oxide grain. It is a fast, cool-cutting grain which produces clean white cuts with minimal surface degradation.
Duralum ® LT is used in the production of bonded abrasives for working heat sensitive steels, alloys, rubber, etc. where a gentle, yet aggressive, action is needed.
Duralum ® LTR is a heat treated calcined form of Duralum® LT that is light blue in color.
This product is recommended for resin-bonded applications where a cool, fast cutting, and extra tough abrasive is desired.
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, and track-grinding wheels. Duralum® Redkote produces significantly improved grinding ratios.
Duralum ® Silkote is a tough, cast fused aluminum oxide abrasive with a clear uniform silane coating added to the grain. Duralum® Silkote produces a stronger, longer lasting resin bonded wheel and can be used in both wet and dry grinding applications.
Duralum ® Silkote is used in grinding wheels and shows the greatest grinding improvements in: cutting-off operations, disc grinding (or any wet grinding application), roll grinding, depressed center wheels, and hot pressed snagging wheels.
