Generally speaking, there are several differences between aluminum alloy wheels and steel wheels, such as the types of vehicles they are used on, weight, and hardness. The specific differences are as follows:

Different Types of Vehicles:
In everyday life, large vehicles like trucks and lorries use steel wheels, while most household cars and SUVs use aluminum alloy wheels. This is because aluminum alloy wheels are more aesthetically pleasing and give a more upscale look when used on household vehicles.
Weight:
Aluminum alloy wheels are lighter than steel wheels because aluminum alloy is a lighter material.
Hardness:
Aluminum alloy wheels have a high hardness due to the inclusion of various metal elements during manufacturing, allowing them to withstand significant pressure. While steel has high inherent hardness, it is still somewhat less hard compared to aluminum alloy wheels.
Heat Dissipation:
Aluminum alloy wheels have better heat dissipation, which allows them to quickly dissipate the heat generated during braking. This extends the lifespan of the tires and braking system and reduces the risk of tire blowouts. Steel wheels have poorer heat dissipation because steel retains heat for a longer period, causing the heat generated by the vehicle to remain within the tire.
Fuel Consumption:
Since aluminum alloy wheels are lighter, they do not require as much power to drive the vehicle, leading to reduced fuel consumption. Steel wheels are heavier, and a portion of the vehicle's power is used to overcome the resistance caused by their weight, resulting in higher fuel consumption.
