Super alloys contain a number of elements in a variety of combinations to achieve the desired result. They have good creep and oxidation resistance. They are available in different shapes, and can be used at very high temperatures and mechanical stress, and also where high surface stability is required. Cobalt-based, nickel-based, and iron-based alloys are three types of super alloys. All of these can be used at temperatures above 540°C (1000°F).
