Dissimilar metals and alloys have different electrode potentials, and when two or more come into contact in an electrolyte, one metal (that's more reactive) acts as anode and the other (that's less reactive) as cathode.The electropotential difference between the reactions at the two electrodes is the driving force for an accelerated attack on the anode metal, which dissolves Three Major periods of metal age in the world are as follows: 1. Intermetallic 58 CE Cerium. Copper and it's many alloys have played an important role in many civilizations, from the ancient Egyptians, Romans to modern day cultures around the world.
