Copper does not rust; it develops a greenish film called patina when exposed to air and moisture. The formation of patina can take several years, depending on the environmental conditions.
The time it takes for a needle to rust can vary depending on the environment. In a humid or damp environment, a needle can begin to rust within hours or days. However, in a dry environment, it may take weeks or even months for a needle to start rusting.
The most common things to rust are iron and steel objects, such as tools, cars, and outdoor furniture. Rust forms when these metals are exposed to moisture and oxygen for extended periods of time.
Iron fillings can start to rust or oxidize in a matter of hours or days, depending on the humidity levels and presence of oxygen in the environment. The process of rusting occurs when iron reacts with oxygen and water, forming iron oxide.
Rust is cause by the oxidation of Iron. Basically, when Iron reacts with Oxygen, Rust is fromed. 2Fe2 + 3O2 ---> 2Fe2O3 (Rust) For this reason, it is only things made out of Iron that can rust. I hope I helped! :)
If they are an alloy, they will eventually rust.
