Non-toxic aluminum-copper round rewound wire is a kind of composite wire composed of two metals, aluminum and copper; non-toxic aluminum-copper round rewound wire is compounded by round wires of two metals, aluminum and copper. Typically, aluminum is the inner conductor and copper is the outer conductor. This design structure combines the light weight of aluminum with the good electrical conductivity of copper to achieve the requirements of more applications.

Non-toxic aluminum and copper round rewound wire offers several advantages. First, the lightweight nature of aluminum results in a lighter overall weight of the wire, making it suitable for weight-sensitive applications. Second, the high conductivity of the copper outer layer provides lower resistance and higher current transfer capability. In addition, aluminum-copper composite construction reduces costs because of the relatively low price of aluminum.


Non-toxic aluminum-copper round compound winding wires are widely used in power cables, transformers, motors, generators and other electrical equipment. They are suitable for applications requiring high current carrying capacity and low weight. Aluminum-copper round rewound wire can also be used to manufacture electronic components such as high frequency coils, inductors and transformers.

Due to the different coefficients of thermal expansion of aluminum and copper, non-toxic aluminum-copper round rewound wire may expand or contract to some degree during temperature changes. This needs to be considered during design and installation to ensure the stability and reliability of the wire.

As aluminum and copper have different melting points and melting properties, the welding of non-toxic aluminum and copper round rewound wire requires special welding processes and techniques. Appropriate measures need to be taken during the welding process to ensure a good welding connection and wire performance.

Non-toxic aluminum-copper round rewound wires are usually non-toxic and meet environmental requirements. They do not contain hazardous substances and can be used in applications where environmental standards need to be met.
