Copper-aluminum composite round wire is a bimetallic conductive round wire covered by copper-aluminum, which is a "new conductor material". It not only has excellent conductive properties of copper, but also has the characteristics of low density of aluminum. It is a "strategic emerging industry" supported by China.
The copper-aluminum composite round wire produced by the company is different from the traditional production processes such as hydrostatic extrusion, rolling and pressing, cladding welding, sleeve rolling, etc., and adopts the original "horizontal continuous casting and efficient molding - rolling" technology, so that the copper-aluminum composite round wire bonding interface reaches a certain metallurgical bonding, and enhances the shear strength of the interface of the two metals. Ensure the mechanical and electrical properties of the product, improve the stability of the product.

1. Electrical equipment manufacturing: mainly including low voltage, medium voltage, high voltage power distribution, busbar system, rectifier, motor winding, etc.;
2. Crane rail supply system, vacuum switchgear, generator set, substation, bimetallic connector in aluminum foil wound transformer, etc.;
3. Wind power, solar photovoltaic field: mainly including reactor, inverter, etc.;
4. Railway, aerospace, high-speed ferry, etc.

1. Unique composite properties, copper-aluminum interface is metallurgical bonding, product performance is high, and it has the characteristics of copper conductivity and low aluminum density;
2. High interface bonding strength, excellent conductivity, excellent mechanical processing performance;
3. The copper layer thickness is large and adjustable, suitable for transmitting large currents;
4. Light weight, convenient transportation and installation;
5. Obvious economic benefits: saving copper resources and reducing production costs.
