I love Metal......the Heavier the better!!!!!!!!!!!!!!!!!!!!!!!!!!!
Yes, Rust = oxidization, so the question should be what metals oxidize and that's most of them. But, to actually rust the metal has to contain iron, because iron oxidation is the process that creates rust and is unique to iron. That limits it to iron and its alloy (metal combined with other elements) steel. According to Wikipedia: Rust is a general term for a series of iron oxides, usually red oxides, formed by the reaction of iron and oxygen in the presence of water or air moisture. Several forms of rust are distinguishable visually and by spectroscopy, and form under different circumstances. Rust consists of hydrated iron(III) oxides Fe2O3·nH2O, iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3. Rusting is the common term for corrosion of iron and its alloys, such as steel. Other metals undergo equivalent corrosion, but the resulting oxides are not commonly called rust. Given sufficient time, oxygen, and water, any iron mass eventually converts entirely to rust and disintegrates. The corrosion of aluminium is extremely slow because the resulting aluminium oxide forms a conformal coating, which protects the remaining aluminium. This process is known as passivation. Aluminum takes a long time to oxidize, copper takes on a green patina that stops it from further oxidization, other metals would eventually decay through oxidization, but only iron rusts. But even elements that we don't think of as metals oxidize like silicon.
Yes. 'Rust' specifically means iron oxide. All other metals oxidize, but only metals that contain iron can 'rust'.
If by 'rust' you mean the redish-brown oxide that remains after oxidation...then the answer to #1 is YES Other metals will not rust unless they contain iron, however they will oxidize( i.e. combine with oxygen and break down)
