Nimonic 80A Rod for High-Temperature Aerospace Components
Nimonic 80A rod is a wrought, age-hardenable nickel-chromium alloy strengthened by additions of titanium, aluminum, and carbon. Developed for service at temperatures up to 815°C (1500°F), it offers excellent mechanical properties, oxidation resistance, and structural stability under thermal stress. This makes Nimonic 80A rod suitable for demanding applications in aerospace, nuclear, automotive, and industrial sectors.
