Copper Alloy

Copper is a kind of metal element, is also a transition element, pure copper is a soft metal, good ductility, high thermal conductivity and electrical conductivity, copper alloy mechanical properties are excellent, low resistivity, among which the most important number of bronze and brass. Moreover, copper is also a durable metal that can be recycled several times without losing its mechanical properties.

Application


Power industry
Power transmission such as cables, transformers, switches, plug-ins and connectors; Motor manufacturing such as stator, rotor, shaft head and hollow wire; Communication cables and residential electrical lines also use a lot of copper wire.
Energy and petrochemical industry
The main condenser tube plate and condenser tube of thermal power plants in the energy industry are made of brass, bronze or white copper. Solar heaters are also often made of copper tubes. Petrochemical industry copper and many copper alloys are widely used in the manufacture of various vessels, piping systems, filters, pumps and valves, various evaporators, heat exchangers and condensers in contact with corrosive media, etc.
Transportation industry
Copper alloys are standard materials in shipbuilding industry. Copper and copper alloys are commonly used as aluminum-bronze propellants, bolts, condensing pipes, etc., in warships and merchant ships. In the automobile and railway industry, copper and copper alloys are mainly used in radiators, brake system pipes, hydraulic devices and power systems, brake friction plates, etc.
Mechanical engineering
In addition to motor, circuit, hydraulic system, pneumatic system and control system with a large number of copper, all kinds of transmission parts and fixed parts, need to copper or copper alloy wear reduction and lubrication. The key component of continuous casting technology of metallurgical equipment - mold, alloy additive copper is an important additive element in alloys such as steel and aluminum. The addition of a small amount of copper to low-alloy structural steels can improve the strength and resistance to atmospheric and Marine corrosion. The corrosion resistance of corrosion-resistant cast iron and stainless steel can be further improved by adding copper to them.
