According to the material can be divided into two categories: steel hub, alloy hub.

1. The main advantages of steel hub are simple manufacturing process, relatively low cost and strong resistance to metal fatigue. But the disadvantages are also obvious, such as large weight, large inertia resistance, poor heat dissipation and so on.

2. The advantages of alloy wheel hub are light weight, high manufacturing accuracy, high strength, low inertia resistance, strong heat dissipation ability, good visual effect, etc. The disadvantages are complex manufacturing process, high cost.
