Copper Applications

Copper has excellent properties of electrical conductivity, thermal conductivity, ductility, corrosion resistance and wear resistance, etc. Widely used in electric power, electronics, energy and petrochemical, machinery and metallurgy, transportation, light industry and emerging industries, etc.

Mechanical and metallurgical industries

In mechanical engineering, in addition to motors, circuit, hydraulic system, pneumatic system and control system in large quantities of copper, all kinds of transmission parts and fixed parts, such as cylinder liner, connectors, fasteners, gears, torsional parts, etc., need copper or copper alloy wear reduction and lubrication.

A small amount of copper added to low-alloy steel can improve its strength and corrosion resistance to atmospheric and oceanic corrosion.

Energy and petrochemical industries

Energy Industry: The main condenser tube plates and condensing tubes of thermal power plants are made of brass, bronze or white copper.

Petrochemical industry: Copper and many copper alloys are widely used in the manufacture of vessels, piping systems, filters, pumps and valves, evaporators, heat exchangers and condensers in contact with corrosive media.

Copper and its alloys are very important materials in marine industry because copper is not only resistant to seawater corrosion, but also has bactericidal effect to prevent fouling of Marine organisms.

Power Industry

Power transmission, such as cables, transformers, switches, plug elements and connectors, etc.

Motor manufacturing such as stator, rotor, shaft head and hollow conductor, etc.

Large quantities of copper wires are also used for communication cables and residential electrical wiring.

Electronics Industry

Electron tube: High frequency and ULTRA-high frequency transmitting tubes, conduits, magnetrons, etc., require high purity oxygen-free copper and dispersion strengthened copper oxygen.

Plated circuit: Copper printed circuits require a large amount of copper foil and copper-base brazing materials.

Integrated circuit: Using copper instead of aluminum in silicon chip as interconnect and lead frame.

Transportation industry

Copper alloys in the marine industry, including aluminum bronze, manganese bronze, aluminum brass, gun copper (tin zinc bronze), white copper and nickel copper alloy (Monel alloy), are all standard materials for shipbuilding.

Automotive industry: Mainly used for radiators, brake piping, hydraulic device, gears, bearings, power distribution and power systems, brake pads, gaskets and various joints, fittings and trim, etc.

Electric motors, rectifiers and control, braking, electrical and signalling systems on railway trains also rely on copper and copper alloys.

Copper is used for wiring, hydraulic, cooling and pneumatic systems in aircraft. Aluminum bronze tubes are used for bearing retainers and landing gear bearings. And diamagnetic copper alloys are used for navigation instruments.

Light industry

Copper and copper alloy can be used in heat exchanger of air conditioner, clock movement, roller, printing copper plate, building decoration components, etc.

Emerging industries and high-tech fields

Such as ultra-low temperature medium containers and pipelines, cooling lining of rocket engines, magnetic winding of high-energy accelerators, etc.
