1. Lightweight
The proportion of aluminum (2.7 g/cm3) is less than half of the iron (7.6 g/cm3) or copper (8.5 g/cm3). As an ideal lightweight material, the potential advantages of aluminum become increasingly clear. In practice, each material selected in auto parts also needs to think about its special design and functional principles. These principles are related to detailed functional goals, for example, mechanical strength, hardness, and component.
The aluminium in cars can not only reduce weight, improve the fuel efficiency, but also can reduce greenhouse gas emissions. Choose lighter material, the characteristics of the material itself can reach the weight loss goals; additionally, the components parts after some processes can reduce the vehicle bodywork weight. For example, the more complex porous aluminum extrusion or high strength thin-walled vacuum aluminum die-castings are expanding a new design space. Designed Audi A8 mold in 1994, in the materials selection also faced with choices: either choose the steel with the total weight as 441 kilograms; or use the aluminum to replace with total weight as 247 kg. Once the final resolution of the models is to use aluminum as car body material, some other rated weight loss approaches are also considered. For example, in order to satisfy the supposed functional requirements set by the vehicle (speed up, gas mileage), a more exquisite initiated machine or fuel tank came into being. According to Audi, such indirect lose weight approaches totally reach the 45 kg weight loss, 23% of the total weight 194 kg. In other words, because of the use of the aluminum auto body, the total weight of the automotive body practicely reduces 239 kg. The discussion of the results of other vehicle weight loss indicated that the ratio of the second weight loss can reach directly 50% -100% weight loss.
2. Safety
Outstanding design and lightweight matrials can reduce the damage and rescue lives. Safety is the preferred elements while manufacturing and buying cars. If accidents happen, the car should keep drivers and passengers safe. Besides, it must reduce the damage as much as possible for all the stuff involved in car crash damage.
