Differences Between Aluminum Alloy Wheels and Steel Wheels
1 Answers
Steel wheels and aluminum alloy wheels differ mainly in appearance and weight. Aluminum alloy wheels are more aesthetically pleasing and lighter in weight. However, aluminum alloy wheels are more expensive, while steel wheels are cheaper. Almost no cars use steel wheels anymore, with most vehicles now equipped with aluminum alloy wheels. The specific differences are as follows: 1. Practicality: Using aluminum alloy wheels can improve handling. Aluminum alloy wheels are lighter, which reduces unsprung mass. Lower unsprung mass enhances the responsiveness of the car's shock absorbers, improving wheel contact with the road. Better wheel contact increases grip, thereby enhancing handling. 2. Heat Dissipation: Aluminum alloy wheels also offer superior heat dissipation, helping to cool tires and brakes. The designs of aluminum alloy wheels are more varied, with some manufacturers even offering custom styles. Therefore, most high-end luxury cars use aluminum alloy wheels. However, aluminum alloy wheels are more prone to damage. If scratched while parking, noticeable marks can form on the surface, which significantly affects appearance. Thus, owners of cars with aluminum alloy wheels are advised to pay close attention to the distance between the tire and the curb when parking.
