Rust is a major issue when it comes to using metal so it’s important to understand which metals rust and how you can both treat and prevent rust.
Rusting Metals
Of all the metals we most commonly use, iron rusts the most. This happens when the metal is exposed to oxygen and water. As steel is an alloy made with iron, it’s also susceptible to rust. However, as it contains non-rusting metals such as chromium and nickel, it is far less likely to rust and is often used in Sheet Metal Fabrication. Aluminium can also corrode, but it is more likely to oxidise, which forms a protective layer and can prevent corrosion.
Anti-corrosion Measures
There’s a number of ways you can prevent corrosion, which all involve creating a barrier between the metal and the elements. Paint and oil are two of the easiest ways to do this, but both require maintenance. Galvanising and powder-coating are more costly but they are both long-term and low maintenance options and are often used in sheet metal fabrication.
Removing Rust
If the corrosion level is low you can remove rust with a scraper or wire wool. Small items can also be rust-treated with WD40, a citric soak, or even a more powerful chemical rust remover, but the latter should ideally be carried out only by professionals.
Choosing the right metal and using preventative techniques are the two best steps in reducing the chance of corrosion, however understanding the ways you can treat rust can also help you keep metal items rust free.
