not reduce performance, but has more advantages<\/h3>\n\n\n\n<p>Some people still have doubts about copper-clad aluminum, believing that it has poor conductivity and is easy to break.<br>However, with the support of Ruichuang&#039;s small-scale composite technology, the performance of copper-clad aluminum materials has been achieved:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Electrical
