What is the difference between aluminum alloy wheels and steel wheels?

[LeElaina]

The differences between aluminum alloy wheels and steel wheels are as follows: 1. Different production costs: Steel wheels have lower production costs, relatively simple manufacturing processes, and are easier to repair when deformed; aluminum alloy wheels involve more complex processing techniques, are prone to breaking upon impact, and are difficult to repair. 2. Different weights: Aluminum alloy wheels have good rigidity and are lightweight. In comparison, steel wheels are much heavier. 3. Different hardness levels: The high density of steel wheels leads to greater weight, which can amplify tire dynamic balance vibrations at high speeds. The heavier weight also increases driving resistance during cold starts, leading to higher fuel consumption during startup. Aluminum alloy wheels have higher hardness and are lighter than steel wheels, resulting in smaller tire dynamic balance vibrations at high speeds and lower fuel consumption during startup compared to steel wheels.
