What metal does not rust in water?
structure changes just enough to become chemically inert and thus unable to react rapidly with additional water molecules or atmospheric oxygen.
This change in molecular structure is why aluminum oxide metal resists corrosion..

What metals form rust?
What Metals Will Form Rust?Iron. Iron will rust very quickly. If iron is allowed to get wet and exposed to air noticeable brown rust can develop in only a few hours. … Aluminum. Aluminum is also mined out of the ground as an oxidized compound called Bauxite. … Copper. Copper rusts from its metallic natural brown shade to a bright green.
What type of metal rusts the fastest?
SteelA. Steel is a refined and very useful form of the element ‘iron’. Copper and bronze do not contain any iron, and only iron can rust (because rust is defined as iron oxide, a compound of iron and oxygen); so the answer is that steel will rust the fastest and copper and bronze will never ever ‘rust’.
