Advantages: Under the same electrical parameters, the conductivity of copper-clad aluminum wire is similar to that of pure copper wire, and its reliability and durability are also high. In addition, the copper-clad aluminum wire is light in weight and relatively low in manufacturing cost.

Disadvantages: copper-clad aluminum wire will expand and deform under high temperature and high pressure, which may lead to wire breakage and cannot be used for a long time. And the conductivity of aluminum is worse than that of copper. In terms of electrical properties, the DC resistance of copper-clad aluminum conductor is greater than that of pure copper conductor. If it is used for power supply, it will lead to extra power consumption and more voltage reduction.
