Cast copper components serve specific functions across multiple industrial sectors, and their applications are closely tied to their material properties. The following is a description by sector.

In the power and electrical industries, the functional role of cast copper components is to conduct electricity and dissipate heat. Cast copper components are used to manufacture contact systems for high-voltage switches, conductive arms for isolating switches, transformer terminals, and generator lead-out terminals. These components require excellent electrical conductivity and a certain degree of resistance to arc erosion. The suitability of cast copper components is verified through electrical resistivity testing and temperature rise tests.

In the shipbuilding and marine engineering sectors, the functional role of cast copper components is to resist seawater corrosion and prevent biofouling. Components such as pump bodies, valve bodies, filter housings, heat exchanger end caps, and propellers within marine seawater systems often utilize tin bronze or aluminum bronze castings. These cast copper components maintain a low uniform corrosion rate in seawater, and certain copper alloys also exhibit a degree of inhibition against marine biofouling.

In general machinery and hydraulic systems, the functional role of cast copper components is to provide wear resistance and sealing. Components such as distribution plates, piston slippers, and bearing cages in hydraulic pumps utilize aluminum bronze or tin bronze castings, leveraging their wear resistance and fatigue resistance. In the valve manufacturing industry, gate plates, valve seats, and sealing rings also employ cast copper components, capitalizing on their corrosion resistance and resistance to abrasion.

In metallurgical and mining machinery, the functional role of cast copper components is heat resistance and impact resistance. Components such as large worm gears for rolling mills, extruder nuts, and crusher bushings are cast from high-strength aluminum bronze. These cast copper components must maintain dimensional stability and wear resistance under heavy loads, low speeds, and conditions involving impact and dust.

In the instrumentation and light industry sectors, the functional focus of cast copper components is precision and aesthetics. Cast brass is used for precision pressure gauge fittings, control valve spools, and gas meter housings due to its excellent machinability, allowing for chrome plating or polishing of the surface. Overall, the functional role of cast copper components varies by application, but their irreplaceability stems primarily from the unique combination of physical and chemical properties inherent in copper alloys.
