铜包铝复合扁排是近几年发展起来的一种高性能低成本的新型复合导体。我国铜排的年需求量大,采用铜包铝复合扁排替代传统铜排可节约大量铜资源,显著降低成本,是国内外发展的重要趋势。铜铝复合材料包括侧面铝裸露型(如三明治结构)和包覆型(横截面上铝完全被铜包覆)两大类。包覆型铜铝复合材料通称铜包铝复合材料,是近几年发展起来的一种新型层状复合材料,兼有铜的导电性能优异、耐腐蚀性能好以及铝的成本低、重量轻等优点。
Copper clad aluminum compound flat row is developed in recent years, a high-performance low-cost new composite conductor. The annual demand for copper bars in our country is large. The use of copper clad aluminum flat bars to replace the traditional copper bars can save a lot of copper resources and significantly reduce costs, which is an important trend of development at home and abroad. Copper-aluminum composites include two types of side aluminum bare (such as sandwich) and clad (aluminum is completely copper coated). Coated copper clad aluminum clad aluminum clad material, commonly known as copper clad aluminum clad laminate, is a new type of layered composite developed in recent years. It has excellent conductivity, good corrosion resistance, low cost and light weight of aluminum advantage.
