Advantages and disadvantages of different hubs

The main advantage of steel wheel hub is that the manufacturing process is simple (generally casting process is adopted, for example, aluminum alloy wheel hub is generally produced by low-pressure casting process). The cost is relatively low, and the ability to resist metal fatigue is very strong, that is, we commonly call it cheap and strong. However, the disadvantages of steel wheel hub are relatively prominent, that is, ugly appearance (it can be said that there is no appearance), large weight (the same wheel hub steel material is much heavier than aluminum alloy material), large inertia resistance, poor heat dissipation, and very easy to rust.

Alloy wheel hub can just make up for such problems. It has light weight, small inertia resistance, high manufacturing accuracy, small deformation and inertia resistance during high-speed rotation, which is conducive to improving the straight-line driving performance of the vehicle and reducing the rolling resistance of the tire, so as to reduce the fuel consumption. The thermal conductivity of alloy material is about three times that of steel and has good heat dissipation. It can play a certain role in the heat attenuation of vehicle braking system, tire and braking system. The alloy wheels of original cars in the market are mainly 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 vision. However, compared with steel wheels, the price of alloy wheels is much more expensive, so often in many middle and low-end original cars, steel wheels will appear on low configuration models, while alloy wheels are standard for high configuration models. https://www.chinaaxle.cn
