Copper or Copper (Cu) plate is a metal with high electrical conductivity, so it is very well used as an electric cable. Copper is insoluble in non-oxidizing acids but copper is oxidized by HNO3 so that copper dissolves in HNO3.
Copper plates are commonly used as busbars or conductors in an electrical panel. The electric panel busbar is very important in its function to distribute electrical energy as needed. Copper plates are also widely used as a craft material, household tools and various industrial sectors.
