Aircraft Alloys & Specialty Metals

Aircraft, Super alloy, or high-performance alloy are intended for high temperature applications – to withstand loading (hold their shape) at temperatures near their melting point – their creep and oxidation resistance are of extremely important Nickel based super alloys have emerged as the material of choice for these applications. The properties of these nickel based super alloys can be tailored to a certain extent through the addition of many other elements, both common and exotic, including not only metals but also metalloids and non-metals: chromium, iron, cobalt, molybdenum, tungsten, tantalum, aluminum, titanium, zirconium, vanadium and carbon are only a few examples of the alloying additions used. Each of these additions has been chosen to serve a particular purpose in optimizing the properties for high temperature application.
