Resistivity of Copper - The Physics Factbook - hypertext

Copper can also maintain solidity at 1083C and boils at 2567C. Like most metals, as the temperature goes up, so does the resistivity. Because of these factors, copper is widely used for electrical purposes such as household electrical wires, electrical machinery and generators and is able to withstand the elements to be used in outdoor power lines.
