In chemistry, the term base metal is used informally to refer to a metal that oxidizes or corrodes relatively easily and reacts variably with diluted hydrochloric acid (HCl) to form hydrogen. Examples include iron, nickel, lead and zinc. Copper is also considered a base metal because it oxidizes relatively easily, although it does not react with HCl.
