Application of traffic aluminum profiles

The specific gravity of aluminium (2.7 g/cm3) is less than half that of steel (7.6 g/cm3) and copper (8.5 g/cm3). The potential advantages of aluminum as an ideal lightweight material are becoming more and more apparent. Of course, this is just a simple comparison. In fact, the material selection for each automotive component also takes into account its specific design and performance criteria. These guidelines are related to specific performance indicators such as mechanical strength, hardness, and weight.

The application of aluminum in transportation can not only reduce weight and improve fuel efficiency, but also reduce greenhouse gas emissions. Selecting lightweight materials, the characteristics of the materials themselves can achieve the purpose of weight reduction; in addition, the parts adopt certain processing techniques, which can further reduce the weight of the car body. For example, more complex metal aluminum porous extrusions, or high-strength thin-walled vacuum aluminum die castings, etc., have expanded new design space.

The combination of superior design and lightweight materials reduces injuries and saves lives. Safety is the number one factor in the design and purchase of a car by manufacturers. When an accident occurs, the car must be able to protect the safety of the driver and passengers. In addition, it must minimize damage to all parties involved in a car crash.

Aluminium is well suited to meet these goals, which is to not only keep the weight as low as possible, but also to maximize the performance. The properties of aluminum alloys make it possible to design cost-effective lightweight automotive components with high strength and excellent crash energy absorption potential. In order to provide the best protection for accident victims, the car is designed to provide a rigid and stable passenger compartment to absorb the impact energy buffer deformation area. For the safety of the car and the safety of all parties involved in an accident, aluminium is the material of choice because it meets requirements such as crash absorption, pedestrian protection and lower maintenance costs.

In addition to structural applications, aluminum alloys are also used in the transportation industry due to their other advantages, such as excellent heat transfer and electrical conductivity. The most obvious examples are radiators, internal combustion engine parts and electric motors.
