Copper is a reddish brown nonferrous mineral which has been used for thousands of years by many cultures. The metal is closely related with silver and gold, with many properties being shared among these metals.
Archaeological evidence suggests that copper is among the earliest metals used by humans. Numerous digs all over the world indicate that copper was used to make utensils, jewelry, and weapons. The metal is highly ductile, meaning that it can be easily worked and pulled into wire. For cultures which had minimal or crude metalworking abilities, copper would have been easy to shape and work with.
Numerous copper alloys exist, many with important historical and contemporary uses. Speculum metal and bronze are alloys of copper and tin. Brass is an alloy of copper and zinc. Monel metal, also called cupronickel, is an alloy of copper and nickel. While the metal "bronze" usually refers to copper-tin alloys, it also is a generic term for any alloy of copper, such as aluminium bronze, silicon bronze, and manganese bronze. Copper is one of the most important constituents of carat silver and gold alloys and carat solders used in the jewelry industry, modifying the color, hardness and melting point of the resulting alloys.
