What materials are car wheels made of? Which one is better?
May 30, 2024
Steel wheel
The term "steel wheel hub" is deeply rooted in people's hearts because of the "mass base". When the automobile industry entered China, due to the limited income level of people at that time, more cars that ordinary people could buy were indeed steel wheels (to be precise, carbon steel, ductile iron, etc.). The advantages of steel wheels are mainly a simple manufacturing process, relatively low cost, strong resistance to metal fatigue, strong load-bearing capacity, etc. Even now, many models of spare tires are still equipped with steel wheels. However, steel wheels also have many disadvantages; for example, ugly appearance, heavy weight, poor heat dissipation, etc., and are prone to rust, which really makes many car owners crazy.
Alloy wheels
In recent years, more and more manufacturers prefer alloy wheels, and modified car owners also choose alloy wheels. Alloy wheels are mainly divided into aluminum alloy wheels and magnesium alloy wheels. The advantages of this material are light weight (helping to save fuel and improve handling), good mechanical properties, high manufacturing precision, strength, heat dissipation, shock absorption, and other indicators are also incomparable to steel wheels, and there is also a lot of room for development in appearance. Although the cost is high, with the mass production and mature technology over the years, the price is completely within the range that ordinary people can afford.
Carbon fiber composite wheel
The name is a bit long and sounds expensive, but this is not an illusion. Wheel hubs made of this material are indeed prepared for car owners who pursue extreme performance. Due to the progress of scientific research capabilities on composite materials in recent years, these materials are also used in the manufacture of automobile wheels. They are light and strong, light and rigid, high temperature resistant, corrosion resistant, fatigue resistant, stable in structure and size, and can be formed as a whole over a large area...
