WebDec 8, 2013 · These are known as the noble metals, "noble" because they stand apart, barely reacting with the other elements. They are also all pretty rare, another important criterion for a currency. WebIntroduction. Bimetallic corrosion can only occur when two dissimilar metals are in ‘electrical’ contact and are bridged by an electrically conductive liquid. The ‘cell’ produced can result in corrosion to one of the paired metals. This can be an issue when stainless steels are in contact with other metals, depending on the circumstances.
