In the automotive industry, for a few years, car manufacturers have been using a new material for their bodies, which is Aluminium. The main reason why they use it is that thanks to its lightness, it complies with the CO2 emissions indicated by the European Union.
Benefits of Using Aluminium for Car Body:
Aluminum has some qualities in addition to which car specialists could not pass away: low density, good corrosion resistance and high thermal conductivity. Specialists say that every ton of aluminum used on the vehicle reduces the emissions of 20 tons of pollution over the life of the vehicle.
The use of aluminum foam also allows the masses of components, systems and systems to be reduced. By using aluminum to make body structures, it is believed that a much-needed goal by specialists around the world will be achieved: lowering fuel consumption below 3 liters / 100 km.
Among the advantages of using aluminum, we must also remember that it is a 100% recyclable metal, with the aluminum recovery rate on scrapped cars currently being over 95% in industrialized countries. At the same time, the re-use of recycled aluminum in the automotive industry makes it possible to achieve 90-94% electricity savings.
There are many benefits to be gained by using aluminum on the car. Particularly, consumer requirements such as safety, performance, fuel economy and environmental protection are improved by:
- Achieving good security: The braking distances are shortened due to the reduction in the weight of the machine. A few meters gained when reducing the braking area can mean avoiding an accident. At the same time, accelerations and decelerations are made more easily in an easier car that becomes more agile and easier to drive.
- Increasing passive security: In case of shock the aluminum profiles absorb by the deformation the higher quantities of the impact energy.
- Reduce fuel consumption: Decreasing the weight of the machine by around 100 kg results in a fuel economy of 0.6 liters / 100 km, and foreign specialists say that, with existing SAF Aluminum alloy technologies, the weight of cars can be reduced by up to 300 kg. This would mean a reduced fuel consumption of 1.5-2 liters / 100 km. With the fuel economy, noxes are reduced. It has been calculated that a 25% reduction in the weight of the machine can also result in a 12.5% reduction in pollutant emissions.
Above we discussed all the benefits of use Aluminium for the Car body.
It has a lower weight than steel, which allows us to obtain a great lightness. High electrical and thermal conductivity, at the time of the fusion welding process much more energy, is needed than in steel welding. When aluminium is combined with oxygen, an oxide layer is created, called alumina, which is what makes it very resistant to corrosion. It is essential to temper the material before doing any operation on it to avoid breakage, due to its fragility. It has a lower mechanical resistance than steel.
