Copper cathodes are sheets of copper that are typically used in the production of electrical conductors, as well as for other purposes. There are several synonyms for copper cathodes that can be used in various contexts. For example, copper plates, copper sheets, and copper strips may all refer to similar materials, depending on their size and shape. Other possible synonyms include copper bars, copper rods, and copper wires, which are all used in the production of different kinds of electrical components. In some cases, the term "copper cathode" may also be used interchangeably with "copper ingot," which refers to a larger block of copper that has been processed into a more uniform shape.
