Base metals are common metals that tarnish, oxidize, or corrode relatively quickly when exposed to air or moisture.
They are widely used in commercial and industrial applications, construction, and manufacturing.
Base metals are non-ferrous industrial metals including copper, nickel, and zinc.
However, base metals are invaluable to the global economy because of their utility and ubiquity.
What is more, some base metals have unique properties that cannot be duplicated by other metals.
Nickel is one of the major components of stainless steel. Zinc goes into galvanizing steel as a protection against corrosion. The Roman Empire used lead for many purposes, including pipes, bathtub linings, cosmetics, and paints.
