Which is better, aluminum alloy wheels or CNC wheels for cars?

Aluminum alloy wheels

1. Diversity in manufacturing processes
   • The manufacturing processes of aluminum alloy wheels include casting, forging, and other methods. The casting process is relatively simple and has a low cost, enabling large-scale production. Therefore, it is relatively affordable in terms of price. For example, many original aluminum alloy wheels of economy cars are made by casting process.
   • The forging process can make the internal structure of aluminum alloy wheels more compact and have higher strength, but the cost is also relatively high.
2. Good performance foundation
   • The aluminum alloy material itself is lightweight, which can reduce the unsprung weight of the vehicle and improve the vehicle's handling performance, fuel economy, and acceleration performance. Generally, compared to steel wheels of the same size, aluminum alloy wheels can reduce the vehicle weight by about 15% - 20%.
   • Aluminum alloy has good thermal conductivity, which helps dissipate heat from the braking system, effectively reducing the risk of brake fade and improving the reliability of the braking system. At the same time, it is also beneficial to prolong the service life of tires.
3. Rich in appearance design
   • Aluminum alloy wheels can achieve different appearance effects through various surface treatment processes, such as painting, electroplating, polishing, etc. These processes can make the wheels present different colors, glosses, and textures, meeting different consumers' needs for personalized car appearance.

CNC wheels

1. High-precision processing
   • CNC (Computer Numerical Control) wheels are processed through precise numerical control programming. It excels in dimensional accuracy and shape accuracy, and can control the dimensional error within a very small range, ensuring that the installation matching degree between the wheel and the vehicle reaches an extremely high level.
   • For some high-performance vehicles or users with extremely high requirements for vehicle handling, this high-precision wheel can reduce vibration and abnormal noise during vehicle driving and provide a more stable and comfortable driving experience.
2. High degree of personalized customization
   • CNC processing technology allows consumers to customize various details of the wheel according to their own preferences, such as unique spoke shapes and personalized pattern engravings. This customized wheel can make the vehicle unique in appearance and show the owner's personality and taste.
3. Optimized combination of high strength and lightweight
   • CNC wheels usually use high-performance aluminum alloy materials, and the structure of the wheel can be optimized during the processing. By precisely removing redundant materials, the wheel can achieve better lightweight effect while ensuring high strength. This is a very important advantage for vehicles that pursue extreme performance, such as racing cars or high-performance sports cars.
