Material Notes:
The newest of the high-performance superalloys invented by Special Metals Corporation, INCONEL® alloy 783 (UNS R30783/US Patent 5,478,417), is an oxidation-resistant, low expansion, nickel-cobalt-iron alloy with aluminum, chromium, and niobium additions. The new alloy is of considerable interest to aircraft gas turbine engine designers and materials engineers for containment and clearance control components such as rings, casings, shrouds and seals for compressors, turbines and exhaust systems. The three-phase age hardenable alloy offers a range of improvements for these applications over alternative alloys in current use.Information Provided by Special Metals Corporation
