Our Nimonic75 high-temperature seamless tubes are built to tackle the toughest conditions, delivering top-notch performance where oxidation resistance and strength are critical. This nickel-based superalloy is a powerhouse for aerospace and other high-heat applications, and we’re here to show you why it’s a cut above, how it fits into industry trends, and what makes our product stand out.
What is Nimonic75 Alloy?
Nimonic75 is a nickel-chromium superalloy engineered for extreme environments. With a high nickel content and a solid dose of chromium, it forms a tough oxide layer that fights off oxidation and corrosion, even at temperatures up to 800°C (and short peaks at 950°C). Its face-centered cubic structure gives it excellent creep resistance and tensile strength, making it perfect for seamless tubing in high-stress applications like turbine blades, combustors, and exhaust systems. Our seamless manufacturing process ensures uniform strength and reliability, with no weak points.
We produce Nimonic75 tubes with precision, using advanced techniques to achieve a flawless surface finish and consistent performance. The alloy is also weldable and can be heat-treated to dial in the exact strength and toughness you need, making it versatile for a range of demanding projects.
