Rupal Metals, a reputable manufacturer and supplier based in Delhi, India, specializes in providing top-notch Nimonic 80A Bars and Rods, perfect for applications that require outstanding heat and oxidation resistance. Crafted from a nickel-chromium alloy enriched with titanium and aluminum, Nimonic 80A is a go-to choice for high-stress, high-temperature settings. At Rupal Metals, we take pride in our precision manufacturing that adheres to international standards, making our products ideal for industries like aerospace, power generation, and heat treatment. With a commitment to durability, reliability, and performance, Rupal Metals ensures that our Nimonic 80A offerings meet even the most demanding engineering challenges.
Nimonic 80A Bars and Rods are primarily made up of nickel (around 70%), chromium (19–21%), along with smaller quantities of titanium (1.8–2.7%) and aluminum (1.0–1.8%). These components work together to deliver exceptional high-temperature strength, oxidation resistance, and creep resistance. The alloy boasts a tensile strength of up to 950 MPa and a yield strength of about 550 MPa, along with impressive fatigue and thermal stability. It retains its mechanical integrity at temperatures soaring up to 815°C. Nimonic 80A can be hardened through precipitation, making it a popular choice for applications where sustained strength at elevated temperatures is crucial.

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 Bars and Rods find extensive use in high-temperature, high-stress environments across various industries. They are commonly utilized in turbine blades, exhaust valves, fasteners, heat exchanger components, and springs within aerospace and gas turbine engines. In the power generation field, you’ll find them in steam turbines and boiler components. Their remarkable oxidation and thermal fatigue resistance also make them ideal for industrial furnaces and nuclear applications. Nimonic 80A is particularly sought after in scenarios where reliability and longevity under extreme thermal cycling and mechanical stress are essential, delivering outstanding performance in demanding conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
