Aluminum Body Repair

While aluminum has been used in racing cars and other performance vehicles for many years, this metal is becoming more common in everyday cars and trucks. While there is a hearty debate over whether or not aluminum is lighter or stronger than the most modern types of high-density steel, high quality auto body shops like Purnell Body Shop need to be prepared to repair vehicles made with both steel and aluminum; we see both every single day. For structural reasons, the two are repaired very differently.

Memory 

The concept of “memory” for materials refers to the material’s ability to move from one position to another and back. Steel has very good memory; aluminum doesn’t. Think of how hard it is to take crumpled up aluminum foil and smooth it back out again; the aluminum has no natural inclination to return to that smooth sheet.

When repairing dents and damage, this is incredibly important. Steel has great memory; using hammers and other tools makes it fairly easy to push steel back into its previous shape. This means that we can push out the dent in your steel door, smooth it out, and repaint it. When we're done, it will look as good as new.

Aluminum, however, has no such memory. Trying to bang out a dent or smooth out a ding can be difficult or impossible because the aluminum simply doesn’t have the physical memory of the spot it used to be in.

Strength 

Steel, in general, becomes weaker when bent. If a steel panel has been bent far enough, or too many times, replacing it may be safer than repairing it. This is because it is more likely to bend again – and bend farther.

Aluminum, however, becomes stronger when it is bent. This means it can be physically difficult to shift something back, especially when you’re looking at an area that was already pressed into a particular shape due to stamping. In fact, the aluminum often cracks if the dent is too deep.

Aluminum-Only Tools and Repairs 

Another factor that you should consider before getting aluminum on your car repaired is that a shop must have aluminum-only tools and aluminum-only bays available to safely work on vehicles. This is because steel and aluminum that are used together will slowly corrode each other over time. Even steel dust can cause corrosion on aluminum body parts.

Aluminum also needs physically different tools because of the issues mentioned above. Essentially, aluminum needs to be repaired differently than steel, and different strategies to do so are required.
