This is an iron-based superalloy which features an austenitic structure with high amounts of nickel and chromium. A286 (or Incoloy) is ideal for high strength and corrosion resistance up to 704°C and for lower stress applications at high temperatures.

Operating aircraft engines at higher temperatures improves energy efficiency and hence fuel efficiency. To do so, aerospace engineers rely on super alloys like Inconel 718 for the hot sections of turbo reactors. Inconel 718 is an age (precipitation) hardened alloy that retains its high yield strength and usability to 1800°F. Did you know that 50% of the Inconel 718 produced is used solely for the manufacturing of aircraft engines in their essential parts including blades, sheets and discs.

Both military and commercial aircraft utilize titanium for its superior strength-weight ratio, helping them to be lighter and more fuel efficient without sacrificing safety and longevity. In addition engine and airframe parts which need to withstand temperature swings from subzero to 600°F utilize titanium’s high temperature strength performance.
