| Rims are produced primarily of three materials: steel, aluminium alloys and magnesium alloys. |
| Different production and mouldings processes are used for each material. This results in rims with different physical and dynamic characteristics. |
| This is the traditionally and most used material due to its good mechanical properties and particularly due to the low costs. The major disadvantage is its weight. |
| This is a popular material due to its specific properties such as light weight and mechanical stability. These properties make the material resistant to the stresses encountered when used on sport cars. However, the costs are higher than for steel. The production and mouldings process consist of cold-chamber die-casting followed by machining. |
| Use of this material is virtually obligatory for racing cars. It is becoming increasingly popular due to its high stability combined with extremely low weight. The costs are higher than for aluminium alloy rims. The production and mouldings process consist of hot-chamber die-casting followed by machining. |
