Copper is a metal used by people who lived in prehistoric times. It is a good conductor of heat and electricity. Jordan, Egypt, and Israel have copper smelting locations that date back to 4500 B.C. The people who lived in that historical period combined copper with iron or tin to produce an alloy called bronze. Another alloy of copper is brass.
