Information
Copper is the 26th most abundant element in the Earth's crust. People have been smelting copper ore to make ornaments, tools and weapons for thousands of years. According to the Copper Development Association, the average American single-family house contains 439 pounds of copper in wiring, plumbing, appliances and hardware.
