Aerospace Materials and Alloys Used in AircraftMaterials such as metal alloys or carbon fiber, help increase the performance of aircraft and reduce transportation costs. Due to their high strength, fatigue resistance, corrosion resistance, temperature resistance, low weight, and load-bearing properties...
These alloys are being used in different aircraft components that have a relative motion, like actuators and track roll units of a control surface. Stress and wear are generated due to the relative motion of these components during takeoff and landing, causing a rise in temperature. And hence,...
As the standards of aircraft performance are raised, possible saving of weight is becoming of ever greater importance, so that more and more interest is being taken by aircraft constructors in metals lighter than aluminium. On January 14, Dr. C. H. Desch, superintendent of the Metallurgical ...

Aluminum alloys have been the primary material of choice for structural components of aircraft since about 1930. Although polymer matrix composites are being used extensively in high-performance military aircraft and are being specified for some applicat
Extensive investigations of TiAl alloys have enabled their commercial implementation in aerospace and automotive industries. The GEnxTM engine is the first commercial aircraft engine that used TiAl (alloy 48-2-2) for their low pressure turbine blades. Among non GE engines, recently, new -stabilised...
Significant progress in the use of magnesium alloys in the developing aerospace industry was observed as early as in the 1940s [5]. Over the last decade, i.e. since the Society of Automotive Engineers (SAE International) imposed a ban on magnesium alloy used in aircraft seat construction, Fe...
Near-alpha alloys are used more often than super-alpha alloys in aircraft because of their superior high-temperature properties, particularly strength and creep resistance. In fact, only one super-alpha alloy is used in significant amounts. Ti–5Al–2.5Sn (IMI317) is used in cryogenic applicati...
This aircraft used Ti-15V-3Cr-3Al-3Sn sheet due to its capability for strip rolling, improved formability, and higher strength than Ti-6Al-4V. The next major usage was on a commercial aircraft, the Boeing 777, which made extensive use of Ti-10V-2Fe-3Al high-strength forgings. Ti-15V-...
Although more costlier than aluminium alloys, magnesium alloys are used where further savings in weight are required. Typical applications are for components for aircraft, material-handling equipment and portable power tools. This is due to the fact that magnesium is two-thirds the weight of ...
