[Better heat dissipation] This is a very important advantage of aluminum alloy wheels. I believe many people know that if the brake heat dissipation performance is not good, the heat cannot be dissipated in time. When it accumulates to a certain level, the heat will decay. The phenomenon will become more and more obvious, and the braking effect will deteriorate over time. At the same time, it may also cause the tire to overheat and burst, which has a great impact on driving safety. The thermal conductivity of aluminum alloy material is 3 times that of steel material, and the heat conduction effect is better. In addition, aluminum alloy wheels usually use narrow spokes to ensure ample heat dissipation space and better air circulation than steel wheels, so It has gradually become the favorite of many models. [Higher Hardness] The hardness of aluminum alloy wheels is higher, so the toughness is insufficient. This is actually a double-edged sword, with pros and cons. The advantage is that there is almost no pro
