Description
Inconel 783
INCONEL® alloy 783 (UNS R30783/U.S. Patent 5,478,417), is an oxidation-resistant, low expansion, nickel-cobalt-iron alloy withaluminum, chromium, and niobium additions. The new alloy is of considerable interest to aircraft gas turbine enginedesigners and materials engineers for containment and clearance control components such as rings, casings, shroudsand seals for compressors, turbines and exhaust systems.
