Aluminum corrodes but it does not rust. When you are talking rust, this only refers to iron and steel corrosion.
Aluminum is actually very prone to corrosion. However, aluminum corrosion is aluminum oxide, a very hard material that actually protects the aluminum from further corrosion. Aluminum oxide corrosion also looks a lot more like aluminum, so it isn’t as easy to notice as rusted iron.
When iron corrodes the color changes and it actually expands. This expanding and color change can produce large red flakes that we all know as rust. Unlike aluminum oxide, the expanding and flaking off of rust exposes new metal to further rusting. This why it is so important to provide a barrier so rust doesn’t start.
How To Produce A Barrier So Rust Does Not Start
Prevent rust is just as important as removing it. While most rust removers do get rid of rust, it is still a lost art for rust products to prevent rust. So what we have developed to assist you in removing rust and preventing it from coming back is a unique organic rust removal kit, which will stop rusty flakes from starting and be assured it will prevent them for up to six months.
