Copper is a non-ferrous metal closely related to human beings. It is not only rich in natural resources, but also has excellent properties such as electrical conductivity, thermal conductivity, ductility, corrosion resistance, and wear resistance.
Main condenser tube sheets and condenser tubes in thermal power plants for the energy industry are made of brass, bronze or cupronickel. Solar heaters are also commonly manufactured using copper tubing.
Copper and copper alloys can be used to manufacture heat exchangers for air conditioners, still pots for watch movements, building decoration components, etc.
In integrated circuits, copper is used instead of aluminum in silicon chips for interconnects and lead frames.
In the shipbuilding industry, copper alloys including aluminum bronze, manganese bronze, aluminum brass, nickel-copper and nickel-copper alloy (Monel alloy) are standard materials for shipbuilding.
Power transmission such as wire cables, transformers, switches, plug-in components and connectors, etc.; communication cables and residential electrical circuits also need to use a large number of copper wires.
In mechanical engineering, in addition to the large amount of copper used in motors, circuits, hydraulic systems, pneumatic systems and control systems, various transmission parts and fixed parts, such as connectors, fasteners, gears, etc.
