Mercedes-Benz wheels are aluminum tubes. Mercedes-Benz is equipped with 21-inch discus five-pair wheels, which are made of aluminum alloy, so that the whole vehicle reflects a strong sense of luxury and refinement.
Mercedes-Benz GLC wheels are cast. Casting is the process of smelting metal into a liquid that meets certain requirements and pouring it into a mold, cooling, solidifying, and cleaning to obtain a casting with a predetermined shape, size, and performance. Forging is a processing method that uses forging machinery to apply pressure to metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes.
How to distinguish between forging and casting:
1. Knock echo: the hub made of good aluminum material is denser, so the knock echo is more crisp. If it is the wheel hub produced by the liquid aluminum forging technology, the sound is the crispest, and the echo may sometimes last for a few seconds. If you find that the echo is dull or almost no echo after tapping, it is better to give up.
2. Observe the surface: except for the excellent surface spraying technology, good wheels rarely have sand holes. And when purchasing, you need to observe each hub carefully to ensure that each hub is not deformed or worn due to packing or transportation.
3. Emphasis on machine inspection: visually check whether the rim is round enough when turning, and give up immediately if the naked eye can observe that it is not round. If it is round, it depends on the weight of the hub. According to the requirements of the original car, it is basically qualified if it is less than 30g.
