Functional profiles made of aluminum play a decisive role in modern vehicle construction, especially in the context of lightweight construction and energy efficiency. These profiles are made from aluminum alloys, which are selected for their specific properties such as low weight, high strength and corrosion resistance. The use of aluminum in vehicle construction is not only a response to the desire to reduce vehicle weight and thereby reduce fuel consumption and CO2 emissions, but it also offers advantages in terms of safety and performance.
One of the main characteristics of aluminum profiles in vehicle construction is their versatility. They can be used in various areas such as frame structures, body panels, roof systems, bumpers and chassis system components. Through advanced manufacturing techniques such as extrusion, bending and joining, these profiles can be formed into complex shapes and structures that are specifically designed for the respective applications in vehicle construction.
Another important aspect is sustainability. Aluminum can be recycled almost indefinitely without any loss of quality, making it an environmentally friendly material. This helps to reduce the ecological footprint of the automotive industry. The recyclability of aluminium is also beneficial from an economic perspective, as it lowers the cost of raw materials while minimizing the environmental impact.
In terms of safety, aluminum profiles offer high energy absorption in the event of collisions, which contributes to occupant protection. This property is particularly important in the construction of vehicle frames and body parts. Despite their light weight, they offer high rigidity and strength, which contributes to the overall structural integrity of the vehicle.
The challenge in using aluminum lies in the development of suitable joining processes, as aluminum has different physical and chemical properties than steel. Innovative techniques such as bonding, welding or mechanical processes such as riveting are used to ensure a durable and reliable connection between the aluminum components.
