**Technical Datasheet: Alloy 80A / Nimonic 80A Rod (UNS N07080)** **1. Introduction** **Alloy 80A**, commercially known as **Nimonic 80A** and standardized as **UNS N07080**, is a nickel-chromium age-hardenable superalloy strengthened by titanium and aluminum additions. In **rod** form, this material provides exceptional high-temperature strength, outstanding creep resistance, and excellent oxidation resistance at temperatures up to 815°C (1500°F). The rod product is particularly suited for machining critical components that must maintain mechanical integrity under severe thermal and mechanical stress conditions. **2.
