The chemical symbol is Cu, with an atomic number of 29, and it is a red metallic element with high conductivity and thermal conductivity. It is relatively abundant in the Earth's crust and is one of the earliest metals used by humans, with a long history. Its physical properties make it widely used in various industrial fields. It is an indispensable material in electrical engineering, used for manufacturing wires, cables, and motors. The conductivity is second only to silver, but it is more common in practical applications due to its lower cost and ease of processing. In addition to electrical applications, copper is also used to manufacture pipes, roofing materials, coins, and various decorations. Equally important in both industrial and artistic fields
