Boiling point 2836 Stable isotopes 2 Heat of vapor. Back Copper Copper is a red, tough metal with a moderately high melting point. It is an excellent conductor of heat and of electricity and finds extensive use as an electric conductor.
Pure copper is soft and can be drawn into wire or hammered into desired shapes.
These shaping processes cause the metal to become hard because the large crystal grains are broken into smaller grains, strengthening the metal. Copper and zinc are alloyed to make brass, and alloyed with tin to make bronze. Alloys of copper and aluminum are called aluminum bronze.
