Aluminum alloy cars also have other advantages. First, aluminum alloy cars reduce the weight of the car without reducing the car's capacity, lower the center of gravity of the body, and improve passenger comfort and safety. Secondly, due to the good energy absorption of aluminum, the car will produce wrinkles during a collision, which can absorb a large amount of impact force and improve the protection of the driver and passengers.
Furthermore, the loss of aluminum in the recycling process of aluminum is only about 5%, and its value rate is the highest among conventional materials used in industry. However, to achieve the ultimate "lightweight" of a car, it is not enough just to use aluminum alloy for the body. In fact, in addition to the body, the car's wheels, chassis, anti-collision beams, floors, power batteries, motor drives/transmission assemblies Cheng and seats can use "light" aluminum alloy, and the quality and performance are superior.
For example, aluminum wheel rims are relatively light in mass, so the moment of inertia is relatively small, which is more conducive to driving and accelerating the car and can also reduce some fuel consumption. And because aluminum alloys are very strong, the spokes of aluminum alloy wheels can be designed smaller, and the holes in the rims are larger, which is more conducive to ventilation and heat dissipation of the braking system.
