It is mainly used to make electrical equipment such as generators, busbars, cables, switchgear, and transformers, as well as heat-conducting equipment such as heat exchangers, pipes, and flat-plate collectors of solar heating devices. The oxygen contained in copper (a small amount of oxygen is easily mixed during copper smelting) has a great influence on the conductivity. Copper used in the electrical industry must generally be oxygen-free copper.

Copper is also used in the production of motor short-circuit rings, electromagnetic heating inductors, high-power electronic components, wiring strip terminals and the like. Copper is also used in doors, windows, handrails and other furniture and decorations.
