How to prevent aluminium corrosion

Rust and corrosion are often used interchangeably to describe the deterioration of metals, but there is a distinct difference between the two terms. Rust specifically refers to the corrosion of iron and its alloys, such as steel, when they come into contact with oxygen and moisture. The reddish-brown flakes that form on the surface of iron or steel are called rust.

On the other hand, corrosion is a general term that describes the degradation of any metal when exposed to environmental elements. Unlike rust, corrosion can affect a wide range of metals, including aluminium, copper, brass, zinc, among others. Corrosion can manifest in various forms, such as pitting, flaking, or discoloration, depending on the type of metal and the conditions in which it is exposed.

The main reason why there is a difference between rust and corrosion lies in the chemical composition of the metals themselves. Iron and steel contain a significant amount of iron, which is prone to reacting with oxygen to form iron oxide, or rust. Other metals, like aluminium and copper, have different chemical compositions that result in different corrosion products when they come into contact with environmental elements.
