描述
铜铝复合板, 又称铜包铝板或铝基覆铜板, 是一种双面铜包铝基板.
采用铝合金板、覆铜板为基材, 由铝合金和铜板复合加工而成.
这种板材结合了铝和铜的优点, 例如铝的重量轻, 良好的韧性, 塑性和导电性, 以及铜优异的导电性, 导热性和耐腐蚀性.
铜 复合铝板 广泛用于许多领域. 在电子、通讯领域, 可作为电路板的高性能基材，制造高可靠性电路板, 并广泛应用于计算机, 通讯, 消费电子等领域.
此外, 也可作为LED的散热器，提高LED的散热效果，延长LED的寿命.
在生产过程中, 铜板和铝板通常需要进行表面处理, 比如酸洗, 碱洗、电解处理, 在涂覆之前以增加其附着力.
镀膜工艺常采用层压工艺，使铜板与铝板在高温高压条件下形成牢固的结合. 然后, 铜包铝也可以进行热处理, 例如退火和固溶处理, 进一步提高其性能.
虽然铜 clad aluminum laminate has many advantages, due to the different chemical properties of copper and aluminum, it may also cause electrochemical corrosion and is difficult to process, requiring a high level of processing technology and equipment.
