    2015 3 19   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.
