Steel vs Aluminium Car Panels – What’s the Difference?

Weight: Aluminium is lighter than steel, which helps cars go further and use less energy. That’s why many electric cars, like Teslas, use aluminium.

Strength: Steel is stronger and bends less easily. Aluminium is strong too, but it can dent or crack more easily.

Rust: Aluminium doesn’t rust, but steel can if the paint is damaged.

Repair: Steel is easier to fix when it gets dented. Aluminium is harder to repair and usually needs heat and special tools. 

Repairing Aluminium 

1. Aluminium Has No “Memory”

Steel has what’s called “metal memory,” which means it naturally wants to return to its original shape when it’s pushed or pulled. Aluminium doesn’t have this property, so it doesn’t bounce back as easily when you’re trying to remove a dent.

2. It’s More Brittle

Aluminium is less flexible than steel. If it’s bent too far or too quickly, it can crack instead of bending, especially when cold. That means technicians have to be extra careful and controlled during repairs.

3. It Often Requires Heat

Because aluminium is stiffer and less forgiving, repairs often require heat to make the metal more workable. Too much heat though can damage the panel or affect the paint, so it’s a delicate balance.
