'''Copper''', the 29th element, is a [[metal]]. In industry it is praised for its extreme [[ductility]] and [[electrical conductivity]] which make it an excellent material for [[wire]]s. Copper is also a nutrient [[mineral]], and is required by the human body to perform certain chemical reactions.

Copper is also important culturally, as one of the first metals to be used by humankind, especially in its alloy form [[bronze]]. Even today the pennies in the United States are informally referred to as "coppers."
