  • What is Copper Corrosion?Definition from Corrosionpedia

     · 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 metal's surface. If this protective film, usually consisting of reddish-brown cuprous oxide (Cu 2 O), is destroyed, then copper will eventually corrode.
