Nimonic 75 (UNS N06075 / W.Nr. 2.4951, 2.4630)

Nimonic 75 (UNS N06075 / W.Nr. 2.4952, 2.4630) is a 80/20 nickel-chromium alloy with controlled additions of titanium and carbon. Nimonic 75 has good mechanical properties and oxidation resistance at high temperatures. It is most commonly used for sheet metal fabrications which require oxidation and scaling resistance together with medium strength at high operating temperatures. Nimonic 75 is also used in gas turbine engines, for components of industrial furnaces, for heat treating equipment and fixtures, and in nuclear engineering.
