Wheel hub is an important part of a wheel. It can be divided into steel, aluminum alloy and composite material wheel hub. The composite material mainly refers to carbon fiber, which has high cost and is not easy to popularize. Its manufacturing process has high technical difficulty and it's not suitable for household vehicles use. Moreover, compared with aluminum alloy wheel hub, although steel has high flexibility, it's also relatively heavy In general, the wheel of the car has high strength and large weight. So it can only be used in a variety of applications.
Features of 18/19/20/21 inch alloy wheels for 2022 NEW MERCEDES-BENZ GLS &SL
The aluminum alloy wheel not only boasts a sleek and stylish design but is also a lighter and more cost-effective alternative to steel wheels.
Advantages
One of the advantages of aluminum alloy is its high expansion rate, which provides good elasticity. Additionally, its excellent thermal conductivity is highly beneficial for efficient heat dissipation in the brake system.

What material are car wheels made of?
There are steel wheels made of steel, as well as common aluminum alloy wheels, and some high-end models use carbon fiber wheels made of new carbon fiber. At present, the more common wheels are aluminum alloy wheels, and there are some practical and economical models that use steel wheels.
Features of car alloy wheels:
1. The aluminum alloy wheel is beautiful and elegant, and it is lighter and more economical than the steel wheel;
2. Aluminum alloy has a high expansion rate, good elasticity, and aluminum alloy has good thermal conductivity, which is very beneficial to the heat dissipation of the brake system;
3. It enhances the braking efficiency, improves the service life of tires and brake discs, and has good rigidity, good roundness, and is not easy to deform;
4. The aluminum alloy wheel has good elasticity, which improves the ride comfort of the vehicle, makes it easier to absorb vibration and noise during movement, and can better ensure the safe driving of the car. The alloy wheels of the original cars on the market are mainly made of aluminum alloy. Of course, many modified wheels will choose chromium, titanium and other elements as the basic materials in order to meet certain special requirements and improve the vision.
Advantages of alloy wheels
Good heat dissipation:
The heat transfer coefficient of aluminum alloy is three times larger than that of steel. During the driving process of the car, 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 wheels can conduct this heat into the air faster than steel wheels, increasing the safety factor.
Lightweight: The specific gravity of the aluminum alloy wheel is smaller than that of the steel wheel, and each wheel is about two kilograms lighter on average than the steel wheel of the same size. A total of eight kilograms can be reduced except for the spare wheel; the lighter wheel can also reduce the resistance when starting and accelerating. , the two work together to make the vehicle more fuel efficient.
High precision: The casting precision of the aluminum alloy wheel is much higher than that of the steel wheel, 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 wheel. These two items can effectively reduce vehicle vibration and make driving more comfortable.
More beautiful: Aluminum alloy has better fluidity and tension than steel wheels in high temperature liquid state, and the later polishing and electroplating process enables it to create a more beautiful and changeable appearance; surface anti-corrosion treatment and electrostatic powder coating also make it timeless as new.
