There are various types of wheels, including cast iron wheels, aluminum alloy wheels, steel wheels, carbon fiber wheels, and so on.

Cast iron wheels: The advantages are low price, strong wear resistance, and corrosion resistance, while the disadvantages are heavy weight, low tensile strength, and difficulty in processing.

Aluminum alloy wheels: The advantages are light weight, high tensile strength, and good processing performance, while the disadvantages are high price and poor wear resistance.

Steel wheel hub: Its advantages are high tensile strength and wear resistance, while its disadvantages are heavy weight, high price, and difficulty in processing.

Carbon fiber wheels: The advantages are light weight, high tensile strength, and good processing performance, while the disadvantages are high price and poor wear resistance.

In summary, different types of wheels have their own advantages and disadvantages, and suitable wheels should be selected based on actual needs.
