![]() ![]() Later, they sent dealers a Technical Service Bulletin that discussed blistering and bubbling under the paint on the aluminum body because of iron contamination. The automaker dismissed the claim and declared that it lacked merit. The post further explained that Ford concealed the problem from buyers and denied the claims. It claimed that Ford used aluminum hoods and did not properly insulate them with old iron-based connecting and supporting parts-knowing that it would result in galvanic coupling and corrosion. As aluminum was the company’s preferred choice, it later faced a lawsuit in the US District Court in New Jersey. Ford is a leading auto manufacturer that has been at the forefront in embracing aluminum at a volume level. Thus, it results in faster corrosion of aluminum and steel.Īn article published in explained how Ford faced a class-action lawsuit when its aluminum hoods experienced corrosion. Due to the high salt concentration, the mixture created is more powerful and efficient at catalyzing corrosion. Rust or corrosion happens because rock salt that is now commonly mixed with magnesium chloride and other salts for de-icing the roads during the winter season are added with bonding agents to keep the mixture from washing away. As oxidation occurs, it hardens and creates a protective layer over the newly exposed areas of corroded aluminum. Therefore, that technically means aluminum can rust.Īluminum oxide appears as a powdery white or dull gray coating. In the narrowest definition of rust, corrosion is interchangeably used with rust. And one of the cons is that it is prone to corrosion. However, just like a coin has two sides, aluminum comes with its share of pros and cons. A growing number of automobile manufacturers are replacing iron and steel with aluminum for many reasons, such as: These include automobiles, nuts, bolts, conductors, airplanes, etc. Unlike rust, which has a flaky, reddish appearance, aluminum oxidation cannot be easily chipped off the metal surface.Īluminum is a common metal that is used widely to produce a variety of products. The aluminum corrosion process is halted by oxidation – the metal won’t continue to deteriorate unless the aluminum oxide is removed. The resulting aluminum oxide is a thin, hard layer that protects the metal from further corrosion.Īluminum oxide appears as a powdery white or dull gray coating. The process of aluminum corrosion is known as oxidation. So does aluminum corrode, or does aluminum rust in water?Ĭars covered by snow on the street on a winter day aluminium doesn’t contain iron or steel so it doesn’t rust – but it is prone to corrosion when exposed to weathering and atmospheric oxygen. Rust is a type of corrosion referring specifically to iron or steel oxidation caused by water or moisture interaction. Corrosion refers to the wearing away of metal caused by a chemical reaction. Rust and corrosion are often interchangeable, but they’re not the same. ![]()
