It is composed of aluminum core wire and copper layer tightly covering its outer surface. It combines the excellent conductivity of copper and the advantage of the light weight of aluminum. It is divided into hard state (H) and soft state (A) according to mechanical properties. It is divided into 10% and 15% according to the volume ratio of the copper layer. Generally, 15% is used in factories.
The density of ECCA wire is 1/3 of that of pure copper wire with the same wire diameter, the DC resistance is about 1.5 times of that of pure copper wire, and the weight of ECCA wire is about 1/2 of that of pure copper wire with the same resistance value. Its welding performance is the same as that of pure copper wire, and it can be used for windings requiring light weight and good heat dissipation, such as audio coils, high-frequency transformer coils, cable TV coaxial cables,... less
