In daily life, many small partners are used to call the wheel hub "steel ring" and "steel basin". Today, I'd like to introduce some mainstream wheel hub materials on the market!

　　1. Steel hub

　　The term "steel basin" is really popular because of the "mass base". When the automobile industry first entered China, due to the limitation of people's income level at that time, the cars that more ordinary people can buy are indeed steel wheels (carbon steel, nodular cast iron, etc.).

　　The main advantages of steel wheel hub are simple manufacturing process, relatively low cost, strong metal fatigue resistance, strong bearing capacity and so on. Even now many spare tires are equipped with steel wheel hub. However, the disadvantages of steel wheel hub are also more; For example, ugly appearance, heavy weight, poor heat dissipation capacity and so on, and easy to rust, which really drives many car owners crazy.

　　2. Alloy wheel hub

　　In recent years, more and more manufacturers prefer the material of the wheel hub, and the refitted car owners will choose more. Alloy wheel hub is mainly divided into aluminum alloy wheel hub and magnesium alloy wheel hub. The advantages of this material are light weight (help to save oil and improve handling performance), good mechanical performance, high manufacturing accuracy, strength, heat dissipation, shock absorption capacity and other indicators of steel wheel hub can not be compared, and the development space of appearance modeling is also large. Although the cost is high, with the mass production and mature technology over the years, the price has been completely within the range that people can afford.

　　3. Carbon fiber composite hub

　　The name is a little long and sounds expensive, which is not an illusion. The wheels of this material are indeed prepared for car owners who pursue extreme performance and "advanced sense". Due to the progress of scientific research 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 It has the advantages of stable structure and size, large-area integral forming... And so on.
