Lighter, durable, sustainable and beautiful than other materials, aluminum is increasingly used in cars, be it trucks, buses, trailers, private cars, etc. If you see the “trunk trucks” in circulation, you may not realize that most of these compartments have almost all aluminum plates.

Why has the use been increased?

Making cars more efficient goes far beyond building products that consume less fuel and thus generate lower levels of pollutant emissions. Decreasing the weight of the assembly by adopting increasingly light materials such as aluminum is critical to achieving a good result. The increasing use of SAF Aluminum is explained by the number of advantages that metal gives. So, basically the main benefits of aluminum in attachments are – excellent corrosion resistance, low specific weight and the good finish that the material provides.

What are its Main Advantages?

• Thanks to alumina, its resistance to corrosion is protected. In contrast, it requires special treatments to increase its thickness.
• Thanks to current technology it is possible to conceive three-dimensional structures lighter and with greater torsional stiffness than the equivalent in steel
Aluminum Foam has a high linear expansion coefficient which allows its dimension to vary when the temperature rises.
• Its strength is its lightness, a third lighter than steel which allows reducing the total body weight up to 40%
• Another noteworthy point is that aluminum bodies tend to be more rigid than steel bodies and incorporate zones of programmed deformation which dissipate a part of the energy produced in an impact.
• On the other hand, this material can be obtained by recycling, using little energy and without losing its qualities which reduces the price of the raw material.
• One of the main benefits is its structural weight which allows vehicles with lower tare (frame weight) and higher load capacity.
• From an engineering standpoint, designers achieve significant weight reductions with high strength alloys.
• It is a corrosion-resistant metal and its high strength-to-weight ratio ensures the success of use in structural designs.
• Aluminum weighs 1/3 less than steel and this lower structural weight means lower fuel, tire, lubricant consumption, less wear on parts.
• Another strength of aluminum is the longer durability of the material because it is immune to oxidation.

Real-time examples of using Aluminum:

The use of lightweight materials also allows for better mass distribution. At Range Rover, chassis and bodies are all aluminum. In Jaguar XE and Discovery Sport, this material is used strategically. Taking weight from the roof and directing it to the floor, on the axles helps reduce the car’s center of gravity while improving traction. Such a “regime” has significant effects on such models. The JEEP car not only became more economical while using aluminum body works but also had improvements in dynamic behavior.

For electric cars too:

Do you know that electric cars are growing increasingly popular nowadays? They can run up to 500 kilometers under ideal conditions. Therefore, weight reduction is as important for electric cars as for combustion engine vehicles. If equipped with the same battery system, a lighter car will need less energy to move around – and thus will have a longer range.
