Consumer durables such as air conditioners and refrigerators utilise copper tubes as heat exchangers because of its excellent thermal conductivity and heat dissipation property. The cathode ray tubes present in televisions as well as magnetron used in a microwave oven are made of copper. It is used in wiring and contacts for mobile phones, televisions, and computers. Copper is used in microprocessors and heat-sinks.
Being an energy efficient metal, copper and its alloys finds various applications in electronics.
