What is Copper Corrosion Definition from Corrosionpedia

What is Copper Corrosion Definition from Corrosionpedia

Mar 19, 2015 Copper is considered to be a noble metal, and as a result is able to resist attack by oxygen.The metal is basically immune to corrosion due to a naturally occurring protective film known as a patina that forms on the metals surface. If this protective film, usually consisting of reddish-brown cuprous oxide Cu 2 O, is destroyed, then copper will eventually corrode.
