Copper metal is abundant and quite inert material with a golden-red color, which is useful for a lot of different things. Copper metal is known since ancient times and was the first metal used by humans. Together with tin, Copper metal is the main ingredient of bronze. In an alloy together with zinc, it forms brass. Copper metal has a very high electrical conductivity, so it is used for most electrical lines (like copper metal wire). Sometimes copper nuggets can be found in nature, but most copper metal is won from ore. Copper also is a necessary trace element for most multicellular organisms.
