Alloy 80A/UNS N07080

Q: Introduction

NIMONIC 80A is a wrought nickel chromium alloy strengthened by titanium and aluminium additions and subsequent aging. It combines elevated-temperature strength, creep resistance and oxidation resistance for service up to approximately 815°C. The alloy is used in turbine hardware, high-temperature fasteners and engine valves. Its performance depends on product form, melting route and the solution treatment and aging cycle selected for the component.

Q: Application

Application areas Gas turbine blades, discs and rings High-temperature bolts and fasteners Nuclear boiler tube supports Die casting inserts and cores Automobile exhaust valves
