Copper clad aluminum enameled wire

Copper-clad aluminum enameled wire is a new generation of high-strength varieties based on copper-clad aluminum wire. It has significant advantages such as light weight and good electrical conductivity. It is worth mentioning that its tensile strength is better than copper-clad aluminum wire of the same specification Increase 30%-40%, can reach 80% of pure copper wire. It overcomes the shortcomings of low-intensity and easy-to-break wire diameter of copper-clad aluminum wire below φ0.5mm, and is the best variety to replace pure copper wire. Copper-clad aluminum enameled wire is a new type of electromagnetic wire using copper-clad aluminum as the inner conductor. Its characteristics are between copper and aluminum, combining the excellent electrical conductivity of copper with the advantages of light weight of aluminum.

Features:

1. DC resistivity: The DC resistivity of copper-clad aluminum wire is about 1.45 times that of pure copper wire; when the resistance is the same, the weight of copper-clad aluminum wire is about 1/2 of that of pure copper wire.

2. Good solderability: Because the copper-clad aluminum wire is concentrically covered with a layer of pure copper, it has the same solderability as pure copper wire without the need for special treatment like aluminum wire; meanwhile, copper The aluminum-clad wire has a thicker copper layer to ensure that the solder performance of the product will not be affected when scraping paint;

3. Light weight: Copper-clad aluminum wire density is 1 / 2.5 of pure copper wire with the same diameter, which is very effective in reducing the weight of the coil; using Shenzhou copper-clad aluminum wire instead of copper wire can save at least 30% of the cost.

Application areas:

1. High-frequency transformers and ordinary transformers;

2. Inductance, electromagnetic coil;

3. Motors, including household motors, various micro-motors and compressors, which have higher environmental requirements;

4. Special electromagnetic wires for audio coils and optical drives;

5. Magnet wire for display deflection coil;

6. Electromagnetic wire for degaussing coil;
