Aluminum wheel repair requires a different process and different tools than working with steel or other metals.
Unlike steel, aluminum doesn’t have “metal memory”. Reshaping aluminum to it’s original design is a more difficult process and requires the technician to have a high level of skill to perform this work.
Steel and aluminum are corrosive to each other. This requires a separate, clean environment dedicated to aluminum repair only. It also requires entirely separate tools that are only used on aluminum. Using tools that have been used for steel repairs can cause damage to aluminum vehicles.
Welding aluminum is a different process, because aluminum conducts heat farther and faster than steel. This means welding aluminum requires special welders and technicians trained to weld aluminum.
Excessive heat can compromise the strength and integrity of the metal, and improper welding can cause safety issues if the vehicle is later involved in an accident.
