Copper is a good electrical conductor. Copper wiring is often a part of a home's electrical system.
Many cooks like the properties of copper pans. They conduct heat well. Some pots or pans have copper on the bottom to conduct the heat to the food, but another metal or ceramic material that does not conduct heat as well to hold the heat in on the sides and top and to make it easier to handle. (Also copper can be expensive so mixed materials may be cheaper.)
Some attribute the terms "Coppers" or "Cops" for police officers to the copper buttons that were on their uniforms.
