The European Union and many other countries such as the United States and Canada have proposed CO2 reduction policies, and the automotive industry must minimize the overall weight of the vehicle while meeting the high safety and aesthetic requirements. To make vehicles more fuel efficient, new engine systems such as electric motors and weight reduction are essential steps. Therefore, lightweight materials, especially aluminum, are crucial.
Vehicle weight is one of the topics of concern for both suppliers and automakers. For every kilogram of weight lost, the vehicle's emissions can be reduced by about 0.08 grams of CO2/km. In addition to the environmental aspects, lightweight construction also improves road safety - both inside and outside the car. This is because lighter vehicles have better handling properties, as well as shorter braking distances.
Ultra-high-strength aluminum in cars could threaten the dominance of steel in this field. Compared to ultra-high-strength steel (UHSS), ultra-high-strength aluminum alloys have the same strength while significantly reducing weight.
6000 aluminum alloys can already easily reach yield strengths of 400 MPa. However, ultra-high-strength steels can provide higher yield strengths of 1100 MPa. But aluminium is lighter, triggering increased demand from OEMs. The aluminum industry has invested heavily in research and development to provide a strong and lightweight alternative to steel.
The main alloying element of 7000 series aluminum is zinc. It also contains smaller amounts of magnesium and copper. The most popular alloys of this group, 7050 and 7075 aluminum, are already widely used in aviation and aerospace. The application in the automotive industry is still in its infancy.
The processing of ultra-high-strength aluminum alloys is similar to that of ultra-high-strength steels, and there are certain challenges in processing ultra-high-strength aluminum alloys. These alloys are more difficult to form than the 6000 series alloys that contain magnesium and silicon.
Aluminium producers such as Haomei will continue to invest in research and development in the coming decades to advance ultra-high-strength alloys and provide automakers with additional options to make their vehicles lighter while sacrificing safety.
