The transition metals are found in the middle of the periodic table. The term non-ferrous simply means not iron. Mercury ordinarily is a fluid; and copper, silver and gold, while having a hardness greater than tin and lead, are not unyielding. Archaeological evidence indicates that copper was used as far back as 10,000 years ago in western Asia.
