Iron is heavier than aluminium. Aluminium is easier to form, shape and machine.
Alloy aluminum is lighter in weight.
Aircraft bodies.
They have streamlined bodies so that they can cut through the wind and air
Aluminium
aluminium alloy
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.
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.
This is because aluminium is not strong enough on its own.
Aluminium is used in the manufacturing of aircraft bodies. It has a low density so the aircraft is lighter and is able to fly easily up in the air.
Because it is stronger and lighter than other alloys, as well as being resistant to most forms of corrosion.
Magnesium is predominantly used in alloys that are strong but with relatively low density, which is important for airplane bodies to increase their energy efficiency.
