The use of aluminium in automotive lightweighting

Lightweighting is the reduction of the overall mass of the vehicle while ensuring the strength, performance, safety and stability of the start, thus ensuring that the vehicle's fuel can be fully utilised and the efficiency of use maximised, providing greater power support for the vehicle and effectively avoiding the use of energy materials and reducing the emission of pollutants. The effect of this is that the vehicle can be used more efficiently.

1. Application of aluminium alloy in the bodywork

The body of the car occupies more than 30% of the overall vehicle mass and consumes more than 70% of the energy. In the actual production of vehicles, the effective use of aluminium alloys for the production of the body can not only reduce the overall quality of the vehicle, but also reduce the cost of the vehicle investment. For example, the Audi A8 is made of all aluminium, and when compared with a traditional car, it can be seen that the body mass of the A8 has been significantly reduced, with the overall mass being reduced by more than 40%, and in the same model, there is a certain difference in terms of crash resistance between the use of aluminium alloys and the non-use of aluminium alloys, with the use of aluminium alloys being significantly better than the non-use of aluminium alloys.

2. Application of aluminium alloys in the chassis

In the process of lightweighting the car, the optimisation of the chassis is not to be ignored and is an easy position to achieve. In the suspension system of the chassis, the use of aluminium alloy material has gradually been paid attention to. Compared with the traditional iron dynamic disc, the weight of aluminium alloy dynamic disc has dropped significantly by about 70%, although the cost of aluminium alloy is higher than the cost of iron, it has increased the service life of the car twice, and the overall view of the cost performance of aluminium alloy is very high. The use of aluminium alloys in the chassis not only satisfies the lightness of the vehicle, but also extends the service life of the components.
