Louis Metals provides Nimonic 80A rods and bars from Houston, USA, meant for aggressive, high-temperature use in nuclear power, gas turbines, and aerospace. The nickel-chromium alloy is precipitation-hardened to provide superior creep strength, oxidation resistance, and mechanical stability under higher temperatures.
Nimonic 80A (UNS N07080) consists mainly of nickel (≈ balance), with 18–21% chromium, 1.8–2.7% titanium, and 1.0–1.8% aluminum. It provides tensile strength up to ~1000 MPa (145 ksi) and yield strength approximately 620 MPa (90 ksi), with a minimum hardness of ~300 HV after aging
. It retains mechanical properties up to ~815 °C and provides strong oxidation resistance

Yes, Nimonic 80A, a nickel-based alloy, can be susceptible to galvanic corrosion when in contact with materials that have significantly different electrochemical potentials, especially in the presence of an electrolyte.
Yes, Nimonic 80A bar can be welded. It is commonly welded using techniques like TIG or MIG welding, with preheating and post-weld heat treatment to prevent cracking.
Nimonic 80A bars are available in various sizes, typically from 6mm to 250mm in diameter, and lengths up to 6 meters. Common finishes include bright, polished, and cold-drawn.
Nimonic 80A rods are applied in turbine blades, components of combustion chambers, exhaust valves, nuclear tube supports, and fasteners for high temperature. Their high-temperature strength and creep resistance make them suitable for gas turbines, jet engines, and aerospace.
