![]() ![]() Over time corrosion will weaken the frame of the vehicle much the same as rust, just not at the same rate. The end result is much the same as crevice corrosion and the fix is the same. Galvanic corrosion happens when aluminum touches a different metal while in the presence of a corrosive liquid and electrical current. To fix this requires the metal to be cleaned and any defects removed before repainting. It will appear like paint bubbling or a separation of paint from the aluminum. This would be the most common form and is treated with a coating or sealant like Krown.įiliform corrosion is more cosmetic and happens after something damages the paint over the aluminum. It will appear like a shallow pit or etching under fittings, joints, seams or hems. In this case the higher the temperature the faster the corrosion happens. Ĭrevice corrosion occurs when a corrosive liquid gets into a crevice and settles. There are three types of aluminum corrosion that can affect your vehicle: crevice corrosion, filiform corrosion and galvanic corrosion. Salt water is the leading cause of aluminum corrosion. It is easy to notice due to its white color. When oxidation occurs with aluminum it is called corrosion and rather than the metal surface flaking away instead a hard skin forms over the metal. Rust as you know will flake off exposing metal underneath which rusts and the whole cycle repeats again and again and again until there is no more metal. But there is a major difference in the end result. Rust can only happen with iron and steel and comes in the form of oxidation but oxidation with aluminum happens as well. CorrosionĪluminum does not rust, so in that regards aluminum already has a leg up on iron and steel. Don’t let anyone tell you otherwise, even if it is with an electric or hybrid vehicle. We have detailed before that yes, it is perfectly safe to spray an aluminum vehicle with Krown. While that is partially true, the elements can attack an aluminum body just the same as a steel body and a Krown undercoating can still help to protect the vehicle. Another reason that is pitched is that aluminum does not rust so your vehicle will not need any expensive rust protection like what we offer at Krown of South Central Pennsylvania. Aluminum is lightweight, which helps make your vehicle more fuel efficient and it is strong as well making your vehicle safer and sturdier. There are many reasons why you might buy a vehicle with an aluminum body and many of them are good reasons too. ![]()
