Luois Metals, located in Houston, USA, specializes in manufacturing and supplying top-notch Alloy C263 Bars and Rods, crafted for outstanding performance in high-temperature and high-stress settings. Known as Nimonic C263, this nickel-cobalt-chromium-molybdenum alloy strikes a perfect balance between oxidation resistance, thermal stability, and ease of fabrication, especially in applications reaching up to 982°C (1800°F). Luois Metals offers Alloy C263 bars and rods in various diameters and conditions, adhering to standards like AMS 5886 and ASTM B637. These bars are perfect for gas turbines, aerospace components, and industrial heat applications.
Alloy C263 Bars and Rods are primarily made up of nickel (the balance), 20% cobalt, 20% chromium, 6% molybdenum, along with trace amounts of titanium and aluminum that enhance precipitation strengthening. This alloy showcases impressive tensile strength (>900 MPa), yield strength (>600 MPa), and remarkable resistance to creep and stress rupture at high temperatures. Alloy C263 maintains its dimensional stability and oxidation resistance even at nearly 1000°C. It’s also weldable and easy to fabricate, making it an excellent choice for high-temperature applications where thermal fatigue and mechanical stress are significant concerns.
