Neil Metals, located in Kolkata, India, has built a solid reputation as a manufacturer and supplier of Nimonic 80A Bars and Rods. They’re well-known for providing top-notch products that are specifically designed to thrive in high-temperature and high-stress environments. These bars and rods are a go-to choice for demanding industrial applications, thanks to their remarkable mechanical strength, resistance to oxidation, and metallurgical stability. Neil Metals offers Nimonic 80A in a variety of sizes, finishes, and custom specifications to align with international standards and the unique needs of different projects. With a strong commitment to precision, quality control, and customer satisfaction, Neil Metals caters to clients in the aerospace, power generation, automotive, and chemical industries.
Nimonic 80A Bars and Rods are primarily made up of nickel (about 76%), with notable amounts of chromium (19–21%), along with titanium and aluminum for precipitation hardening. This unique blend gives them outstanding tensile strength, creep resistance, and oxidation resistance at high temperatures, reaching up to 815°C. The alloy boasts a tensile strength of around 125 ksi (860 MPa) and impressive fatigue resistance, making it ideal for extended use under thermal and mechanical stress. It can also be heat-treated to boost its strength and stability even further.
