I believe that when it comes to aluminum alloy wheels, you must be familiar with all of you, right? After all, wheels are now weighed or compared when buying a car. After all, aluminum alloy wheels have incomparable advantages over steel wheels, and they have a slight impact on appearance and driving. However, are aluminum alloy wheels really helpful to our driving?

First of all, the biggest advantage of aluminum alloy wheels compared with iron wheels is heat dissipation. The heat transfer coefficient of aluminum alloy is three times larger than that of steel. As we all know, the friction between the tire and the ground and the brake disc and the brake pad will generate high heat during the driving process. This situation will cause the tire and brake pad to age and accelerate wear. The braking performance will be sharp due to high temperature. Attenuation, the air pressure in the tire will also increase and there is a hidden danger of puncture. Aluminum alloy wheels can conduct these heat into the air faster than steel wheels, which increases the safety factor.

Secondly, the weight of aluminum alloy wheels is less than that of steel wheels. On average, each wheel is about 2 kg lighter than steel wheels of the same size, so the total weight will be about 8 kg. As the saying goes: "One kilogram on the sprung, ten kilograms on the sprung", which means that one kilogram lightened under the unsprung is equivalent to ten kilograms lighter on the sprung. Or be more flexible when cornering, which can also reduce fuel consumption to a certain extent.

Of course, the manufacturing process and inspection process of aluminum alloy wheels are much more complicated than steel wheels. The precision of casting of aluminum alloy wheels is much higher than that of steel wheels, with less roundness and unbalanced weight. In addition, aluminum alloy has a small elastic modulus, and its anti-vibration performance is better than that of steel wheels. These two items can effectively reduce vehicle vibration and make driving more comfortable.
