The most common metals used in aircraft construction are aluminum, magnesium, titanium, steel, and their alloys. An alloy is composed of two or more metals. The metal present in the alloy in the largest amount is called the base metal. All other metals added to the base metal are called alloying elements.
What materials are used to make airplanes?
Most airplanes today are made out of aluminum, a strong, yet lightweight metal. The Ford Tri-Motor, the first passenger plane from 1928, was made out of aluminum. The modern Boeing 747 is an aluminum airplane as well. Other metals, such as steel and titanium, are sometimes used to build aircraft.
What are the most widely used material for aircraft construction?
Titanium and its alloys are commonly used in the construction of aircraft due to its high strength properties, high-temperature resistance and high corrosion resistance compared to steel and aluminum. Despite being expensive, titanium is used in aircraft construction due to its excellent material properties.
Which material is used for the construction of aircraft fuselage?
Aluminium alloy has been the most common fuselage material over the past eighty years, although carbon fibre-epoxy composite is regularly used in the fuselage of military fighters and increasingly in large passenger aircraft. For example, the Boeing 787 fuselage is constructed using carbon-epoxy composite.
What is the primary property of material for use in aircraft?
One of the most important properties of a material is strength. Strength is the ability of a material to resist deformation. Strength is also the ability of a material to resist stress without breaking.
Why Aluminium is used in aircraft?
Aluminum is ideal for aircraft manufacture because it’s lightweight and strong. Aluminum is roughly a third the weight of steel, allowing an aircraft to carry more weight and or become more fuel efficient. Furthermore, aluminum’s high resistance to corrosion ensures the safety of the aircraft and its passengers.
Why is titanium used in aircraft wings?
Strength. Titanium offers the strength of steel at about half the weight. During flight, aircraft wings provide the lift and the rest of the aircraft, basically, hangs from the flying wings. … This high stress area requires a very strong metal like titanium, which is as strong as some types of steel.
Why are composites used in aircraft?
Composite materials are important to the Aviation Industry because they provide structural strength comparable to metallic alloys, but at a lighter weight. This leads to improved fuel efficiency and performance from an aircraft.
What alloy is used in aircraft?
Aluminum alloys are widely used in aircraft fuselages and other engineering structures and compounds in which light weight and corrosion resistance are highly desired.
What metals properties are essential in aircraft manufacturing?
Of primary concern in aircraft maintenance are such general properties of metals and their alloys as hardness, malleability, ductility, elasticity, toughness, density, brittleness, fusibility, conductivity contraction and expansion, and so forth.
What are the types of fuselage construction?
There are two general types of fuselage construction—welded steel truss and monocoque designs. The welded steel truss was used in smaller Navy aircraft, and it is still being used in some helicopters. The monocoque design relies largely on the strength of the skin, or covering, to carry various loads.
What are the main parts of an aircraft?

What are the 3 major axis of an aircraft?
Regardless of the type of aircraft, there are three axes upon which it can move: Left and Right, Forwards and Backwards, Up and Down. In aviation though, their technical names are the lateral axis, longitudinal axis and vertical axis.
What qualities are important for materials for aircraft?
Aircraft materials are required to possess a high strength to weight ratio, superior fatigue characteristics, and withstand a wide range of temperatures.
What is airplane wings made of?
Airplane wings are made out of aluminum — although not the same aluminium in cans and tin foil. It’s aerospace grade stuff, an alloy with strength comparable to steel. In addition to the wings being constructed from high-power materials, there’s a hidden support system within each wing.
What are some of the properties of steel?
Steel has a number of properties, including: hardness, toughness, tensile strength, yield strength, elongation, fatigue strength, corrosion, plasticity, malleability and creep.
