Nimonic 75 Bars and Rods are top-notch products made from a nickel-chromium alloy, celebrated for their exceptional resistance to heat and oxidation. Designed to handle tough service conditions, these materials perform reliably even in high-temperature and corrosive environments, making them a go-to choice for aerospace, chemical, and power-generation applications. With impressive mechanical stability, good ductility, and resistance to scaling at elevated temperatures, they ensure dependable operation. Thanks to their superior fabricability and strength retention, Nimonic 75 Bars and Rods are the preferred option for components that need to hold up under thermal stress.
This alloy primarily consists of nickel (around 75%) and chromium (about 20%), along with small amounts of titanium, aluminum, carbon, and iron to enhance strength and stability. It boasts excellent oxidation resistance up to 1000°C and maintains good creep and tensile strength at high temperatures. Its strong yield characteristics, decent ductility, and stable mechanical behavior make it easy to work with and shape. These combined features allow the material to perform consistently, even under prolonged exposure to high temperatures.
