That the inner layer uses a special aluminum alloy core material, and the outer layer is covered with a high-purity copper layer. It is made through a continuous coating and drawing process. Compared with ordinary copper-clad aluminum, its tensile, stretching, and bending resistance are greatly upgraded, and its dimensional accuracy is higher.
1.The aluminum alloy core enhances mechanical strength, making it less prone to breakage and suitable for high-speed winding.
2.It is corrosion-resistant, creep-resistant, and has a longer service life than ordinary copper-clad aluminum.
3.Stable electrical conductivity, lightweight and high strength;
4.It has excellent welding performance and is compatible with conventional soldering processes.
Application areas include precision motors, miniature transformers, sensor leads, automotive electronic wiring harnesses, high-end home appliance wiring, and precision connection wires for industrial control equipment.
