Aluminum Magnet Wire is a kind of enameled wire used more and more at present, which is inseparable from its own performance characteristics. Aluminum magnet wire not only retains some advantages of copper but also has more advantages in weight and cost. Therefore, it has won the favour of many users, and with the continuous progress of aluminum magnet wire, there will be more applications in the future.
Specifically, the aluminum magnet wire has high heat-resistant temperature, good thermal shock and softening breakdown performance, is suitable for high-speed automatic winding, and also has the characteristics of high breakdown voltage, no pinholes, direct weldability, high-frequency resistance, small dielectric loss angle and the like, and has good abrasion resistance, and in addition, the pulsing life of the aluminum magnet wire can reach tens of times of that of common composite enameled wires.
Compared with copper magnet wires, aluminum magnet wires have a higher heat resistance rating of about 20℃ than copper magnet wires. However, when the copper conductor is changed into aluminum conductor, only the conductor diameter needs to be enlarged by 14.7%, and other performance parameters are unchanged. The original 1 ton copper magnet wire needs only 0.4 ton to be changed into aluminum magnet wire, which is about 40% of the weight of copper, and the cost is only over 20% of that of copper magnet wire.
