Wheel hubs in the market can be divided into steel wheel hub and alloy wheel hub according to the material, and each has its own advantages and disadvantages.

The main advantage of the steel wheel hub is that the manufacturing process is simple (generally using the casting process, such as aluminum alloy wheel hub generally using the low-pressure casting process production), the cost is relatively low, and the ability to resist metal fatigue is very strong, which is commonly known as cheap and strong. However, the disadvantages of steel wheel hub are relatively prominent, that is, ugly appearance (no appearance to speak of), heavy weight (the same wheel hub steel material is much heavier than aluminum alloy material), large inertia resistance, poor heat dissipation, and easy to rust.

Alloy wheel hub just can make up for such problems, light weight, small inertia resistance, high manufacturing accuracy, small deformation when rotating at high speed, small inertia resistance, which is conducive to improving the straight-line driving performance of the car, reducing tire rolling resistance, thus reducing fuel consumption. The thermal conductivity of alloy material is about three times that of steel, with good heat dissipation, which can play a certain role in the thermal attenuation of vehicle brake system, tire and brake system. The alloy wheels of the original cars in the market are mainly made of aluminum alloy. Of course, many modified wheels will choose chromium, titanium and other elements as basic materials in order to meet certain special requirements and improve the vision. However, compared with the steel wheel hub, the price of alloy wheel hub is much more expensive. Therefore, the steel wheel hub will appear in the low-end model in many original cars, and the alloy wheel hub is the standard for the high-end model.
