However, it does get corroded which is another type of oxidation reaction. So, technically, rusting is the property limited to iron and related compounds.Ĭopper does not undergo rusting. It results in the formation of a reddish or yellowish-brown colored coating on the surface which is known as rust. As Copper is susceptible to losing electrons, it undergoes oxidation when exposed to air and humid environment and gets corroded over time.Īctually, rusting is a type of oxidation reaction that occurs particularly in iron and its metal alloys when they are exposed to air and water like in a humid environment. Unlike rusting copper forms a bluish-green color layer on its surface, known as patina after corrosion, resulting in tarnishing its lustrous surface. However, it undergoes oxidization or corrosion. So, does Copper rust? No, Copper does not rust. In this article, we will check out whether copper also rusts like iron. Copper finds its use in different industries like construction, electronics, etc., and also in decorative items. It also forms an essential trace element for most living organisms. It is malleable, ductile and a good conductor of heat as well as electricity. Copper has the atomic number 29 and belongs to the d-block of the periodic table.
