Aluminum alloy wheels have won the favor of more and more private car owners because of their beautiful appearance, safety and comfort. Now, almost all new models use aluminum alloy wheels, and many car owners have also replaced the original wheels with aluminum alloy wheels. Alloy wheels are mostly made of aluminum as the basic material, with appropriate addition of manganese, magnesium, chromium, titanium and other metal elements. Compared with steel wheels, alloy wheels have the characteristics of energy saving, safety and comfort, so more and more cars have listed alloy wheels as standard configuration.

Compared with traditional steel rims, the main advantages are as follows:
Good heat dissipation
The heat transfer coefficient of aluminum alloy is three times larger than that of steel. During driving, the friction between the tire and the ground and the brake disc and the brake pad will generate high heat, which will lead to the aging of the tire and the brake pad and accelerated wear, and the braking performance will be sharply attenuated due to high temperature. The air pressure in the tires will also increase and there is a danger of a tire blowout. Aluminum alloy rims can conduct this heat into the air faster than steel rims, increasing the safety factor.
light weight
The specific gravity of aluminum alloy rims is smaller than that of steel rims, and each is about two kilograms lighter on average than steel rims of the same size. A total of eight kilograms can be reduced except for the spare wheel; lighter rims can also reduce starting and acceleration. resistance, the two work together to make the vehicle more fuel efficient.
High precision
The casting precision of the aluminum alloy rim is much higher than that of the steel rim, and the out-of-roundness and unbalanced weight are smaller; in addition, the elastic modulus of the aluminum alloy is small, and the anti-vibration performance is better than that of the steel rim. These two items can effectively reduce vehicle vibration and make driving more comfortable.
more beautiful
Aluminum alloy has better fluidity and tension than steel rims in high temperature liquid state, and the post-polishing and electroplating process enables it to produce a more beautiful and varied appearance; surface anti-corrosion treatment and electrostatic powder coating also make it durable like New.
