Aluminium in a Car

For years, aluminium has been used in the manufacture of vehicles. Currently, the transportation industry consumes almost 30% of the total aluminium consumption globally, comprising the largest consumer of aluminium across industries. In the transportation industry, it is used in the manufacture of vehicles, aircrafts, spaceships, ship and other vessels. But what car and vessel parts are made from aluminium flat bar?

Car parts made using aluminium

The body and frame of the vehicles are primarily made from aluminium. The electrical wiring, the transmission components, pistons, cylinder heads, radiators, the magnets used in speedometers, airbags and tachometers, the lamps, air conditioner condenser, electrical wiring, wheels and air conditioner pipes are also made from aluminium.


The number of parts made from aluminium may vary from one car manufacturer to the other. For example, electric vehicles utilise more aluminium that diesel or petrol fuelled vehicles. As more innovations come up, the level of aluminium is also bound to increase.


What are the benefits of using aluminium in the manufacture of vehicles?

The use of aluminium decreases the weight of the vehicle which has a great effect on the speed of the vehicle. The lower the weight of the vehicle, the better the acceleration, the more efficient Aluminium is also cost efficient which ultimately decreases the cost of the manufacture of the cars. These cost benefits are later passed on to consumers through lower vehicle prices. Its strength also ensures that the vehicles and other transportation vessels are safe for use even at high speed which is made possible by its ability to absorb higher crash energy. It is also associated with greater fuel efficiency compared to steel therefore lower maintenance costs.


The malleability of aluminium ensures that it can be moulded into any shape, in any size. This combined with its flexibility makes it easier for manufacturers during the manufacturing and assembly of different vehicles. In addition to this, it is a good conductor of heat and electricity making it ideal for car parts that utilise these qualities.


When aluminium is exposed to oxygen, the reaction results in an oxide layer, albeit thin. This layer coats the aluminium and protects it from further corrosion. This ensures that the vehicle remains in good shape even when exposed to substances that would accelerate corrosion. This enhances the durability of the vehicle and reduces the maintenance costs since the vehicle does not rust.


Being recyclable, over 90 % of aluminium can be recycled at the end of the useful life of the vehicle and this has great environmental benefits. It is good to note that it can be recycled over and over without losing its quality and functionality. Therefore, aluminium offers an environmentally friendly, cost effective and safe way to improve the efficiency and performance of vehicles compared to other substances.


The auto industry is a great beneficiary of aluminium. The quantities used over the years have been on an upward trajectory and is expected to continue this way in the foreseeable future. The future of the automotive industry will greatly rely on aluminium.
