"It depends on the application. Aluminium does not rust as it does not contain iron, however in the saltwater environment it is susceptible to something called electrolysis, this does corrode the material. Otherwise the material takes on a sort of oxidisation as it’s exposed to the elements. Its a lovely material though, strong, light."

"Aluminium does not rust, but it does corrode, although it's hard to spot due to having a similar colour"
