Project Description

Nimonic 75 (UNS N06075)

Nimonic 75 (UNS N06075) 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. 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 (Nimonic 75) is also used in gas turbine engines, for components of industrial furnaces, for heat treating equipment and fixtures, and in nuclear engineering.
