* Steel: This is the most common and least expensive material. Steel rims are strong and durable, but they are also heavier than other options. They are often painted or coated to prevent rust.
* Aluminum Alloy: Aluminum alloy rims are lighter than steel rims, which improves fuel efficiency and handling. They're also stronger than steel for their weight and can be styled in more complex designs. They are more expensive than steel.
* Magnesium Alloy: These are even lighter than aluminum alloys, offering superior handling and performance benefits, particularly in high-performance vehicles. However, they are also the most expensive and are more susceptible to corrosion.
* Carbon Fiber: While becoming more common in high-end vehicles and racing, carbon fiber rims are extremely lightweight and strong. They are also the most expensive option and require specialized manufacturing techniques.
The specific composition of the alloy (for aluminum and magnesium) can vary depending on the manufacturer and desired properties.
