Nimonic 80A is a nickel-chromium alloy that’s enhanced with cobalt and titanium, providing remarkable high-temperature characteristics. Typically, it consists of about 50–55% nickel, 19–21% chromium, 2–3% titanium, 4–5% cobalt, along with small amounts of aluminum and carbon, which gives it exceptional creep and oxidation resistance. This alloy boasts a tensile strength of roughly 900–1,000 MPa at room temperature and maintains significant strength even at temperatures exceeding 700°C. Its mechanical properties include high fatigue resistance, excellent stress-rupture performance, and dimensional stability under extended thermal exposure, making it a go-to choice for critical high-temperature components in challenging environments.
