I think that srtonger metals like gold do not rust. I also think that some metals, when combined with others do not rust, like when you combine iron with aluminum, it doesn't rust.

By definition, the only metals that rust are iron and iron alloys. Even so, not all iron alloys rust. Stainless steel (an iron alloy) does not rust.

Gold doesn't rust, in that it doesn't combine with oxygen from the atmosphere to form a surface of gold oxide. But it can tarnish, that is, for a thin transparent darker layer to form on the surface. however steel will rust. to protect a metal from rusting you must galvanzie it or paint. for example to galvanzie iron you must use a metal higher in the electrochemical series like zinc. this will protect it from rusting.

No, not all metals rust. Rust itself is iron oxide and comes about when iron metal oxidises; therefore only Iron rusts.

What will not rust?

Iron is the only thing that can rust. I think that is not possible to give a correct answer. Even iron if it's protected, by paint.., will never rust.. Rust is a term to describe the oxide, better a family of oxides, that develop on iron or steel when it corrodes. Other metals does not rust but corrodes and develops other types of oxide.


What metals dont rust?

Metals such as gold, platinum, and silver are highly resistant to rusting because they do not easily react with oxygen in the air. Stainless steel, which contains chromium, is also known for its rust-resistant properties.
