Super alloys have good creep and oxidation resistance, and can be formed in different shapes. They contain a number of elements in a variety of combinations to achieve the desired result, and can function at very high temperatures and mechanical stress. They are classified into three groups such as nickel-based, iron-based and cobalt-based alloys. Nimonic 90™ is a nickel-chromium-cobalt alloy which can be strengthened by adding aluminum and titanium. Chemical Composition The following table shows the chemical composition of Nimonic 90™. Element Content (%) Iron, Fe 58.5 Chromium, Cr 19.5 Cobalt, Co 18 Titanium, Ti 2.5 Aluminum, Al 1.5
