Nimonic Alloy 75 (UNS N06075) is a nickel-chromium alloy with good mechanical properties and oxidation resistance at high temperatures. Alloy 75 is most commonly used for sheet metal fabrications which require oxidation and scaling resistance together with medium strength at high operating temperatures. Alloy 75 is also used in gas turbine engines, for components of industrial furnaces, for heat treating equipment and fixtures, and in nuclear engineering.
Availability
Alloy 75 is available in Bar, Plate, Strip, Sheet, Wire, Tube, Rod, Forging Stock and Extruded Section.
