Zinc and Cadmium - University of Denver

The metal cadmium will also appear, since it is similar to zinc and closely associated with it, and is also useful, though much less used. The largest use of zinc is as a protective coating for iron. The process is called galvanizing with reference to the cathodic protection the zinc offers to the iron.
