Advantages and disadvantages of aluminum alloy wheels?

The advantages of aluminum alloy wheels include:

Lightweight: The density of aluminum alloy wheels is about one-third that of steel, which means that aluminum alloy wheels of the same volume are much lighter than steel wheels. This helps reduce the overall weight of the car, improve fuel efficiency, and enhance the vehicle's handling performance.
Good heat dissipation performance: Aluminum has a much higher thermal conductivity than steel, so aluminum alloy wheels can more effectively dissipate the heat generated during braking, reduce overheating of tires and braking systems, and improve driving safety.
Aesthetics: Aluminum alloy wheels can be made into complex shapes through precision casting technology, and can be polished and electroplated to obtain various colors and luster, making the vehicle's appearance more fashionable and personalized.
Energy saving: Due to its lightweight and good heat dissipation performance, aluminum alloy wheels help reduce vehicle energy consumption and environmental pollution.
Safety: The high strength and good heat dissipation performance of aluminum alloy wheels can improve driving safety and extend the service life of tires and braking systems.

The disadvantages of aluminum alloy wheels include:

High cost: The manufacturing process of aluminum alloy wheels is relatively complex, and the cost is usually higher than that of steel wheels.
Easy to deform: Although aluminum alloy wheels have high strength, they may deform when subjected to severe impacts, and once deformed, they are often difficult to repair and require replacement with new wheels.
Corrosion resistance: Although the surface of aluminum alloy wheels is usually treated for corrosion resistance, corrosion may still occur in certain environments.
Sealing ring issue: In high-temperature environments, the sealing ring on aluminum alloy wheels may accelerate aging, leading to oil leakage and other problems.
