Aircraft must be light and strong, simultaneously. Aluminum is the lightest metal on the Periodic Table, meaning that it has the strength and tensile properties of most metals, but is only about half as heavy as most of the other common metals, such as titanium, copper, or iron. It is therefore the optimum material to use in aircraft design. However, aluminum may be phased out as more high-tech or sophisticated materials enter the market, such as carbon nanofibers (elemental carbon is less than half as heavy as pure aluminum metal).

Why is cryolite used in the manufacture of aluminium?

It's used as a flux. It melts at a significantly lower temperature than aluminum oxide ores, but they will dissolve in molten cryolite. This means less energy is required to extract the aluminum from the ores than if they had to be heated to their melting temperatures.


Why was alloys of aluminium are used to make aircraft bodies instead of pure aluminium?

Pure aluminum isn't used for ANYTHING--even a cola can is made from aluminum alloy. Aerostructures are made from various aluminum alloys chosen for their strength, workability or other desirable characteristics.


Why is aluminum an important element?

Aluminium is light and strong. It is used extensively in the manufacture of planes, space shuttles also in the building industry. It is more expensive than steel to manufacture so steel is still used extensively where weight is not a problem.


What is an aluminium gallium arsenide?

Aluminium gallium arsenide (AlGaAs) is a semiconductor compound made of aluminium, gallium, and arsenic. It is commonly used in electronic and optoelectronic devices, such as lasers and solar cells, due to its unique properties like bandgap tunability and high electron mobility. AlGaAs is often used in applications that require precise control over the properties of the material for enhanced performance.


What is the element used in aircraft?

Aluminum-magnesium alloys are used in making parts in aircraft. Aluminum-magnesium alloys are lighter than other aluminum alloys and much less flammable than alloys that contain a very high percentage of magnesium.Aluminum alloys are alloys in which aluminum (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon and zinc.Aluminum alloys are widely used in engineering structures and components where light weight or corrosion resistance is required.Alloys composed mostly of aluminum have been very important in aerospace manufacturing since the introduction of metal skinned aircraft.
