Can aluminum alloy wheels be repaired?

Under normal conditions, if your aluminium Alloy Wheels are deformed or broken, it must be due to the careless driving that causes the hub to be subjected to strong external impact.

So can the aluminum alloy hub be repaired? We can hereby responsibly tell everyone not to try to repair the wheels that have been deformed and broken. Continue to use such a repair wheel can be very dangerous!

According to the advertisement of the roadside shop, the fracture or crack of the aluminum alloy hub can be repaired by welding, but from a scientific point of view, the metal crystal structure at the weld after welding is completely different from that of the normal hub. The metal of the normal hub is cooled and crystallized gradually under a certain pressure in the molten state, and then undergoes solidification and actual treatment for quenching and tempering. Welding is only a process of partial melting and solidification. After the welded hub, there must be weld stress at the weld seam. After a certain period of load operation, fatigue cracks are likely to occur in the high stress area of the hub. If it is found that it is not timely, it may cause serious consequences.

Similarly, if your aluminum alloy wheel is deformed by an external force and deformed, it is forcibly restored to the original state by an external force at the repair shop. Even if your hub is plastically deformed twice, it is fortunate that it will not produce fine cracks that cannot be found by the naked eye. The overall stress distribution of this wheel hub has also undergone major changes with the original design, which is followed by an unpredictable occurrence of fatigue cracks somewhere, followed by fracture.

As for the scratches on the surface of the hub, we recommend that small scratches do not have to be dealt with, because the scratches mainly appear on the Staggered Wheels. If aesthetic reasons, you can choose to use this wheel as a spare wheel. . Aluminum, a metal, has the property that it is exposed to a corrosive environment for a long period of time, and its surface will form a dense oxide protective film to prevent further oxidation of the body, so there is no need to worry about it being corroded.
