單/雙面銅鋁復合板帶
Single/double sided copper aluminum composite strip特性優點 Character
單面或者雙面銅復鋁，幾乎沒有接觸電阻，與純銅相比有超過70%的重量優勢，擁有非常好的導電率和導熱率以及散熱性，具體可根據需求定制。
Single-sided or double-sided copper composite aluminum alloy, almost no contact resistance, compared with pure copper has more than 70% weight advantage, has very good conductivity and thermal conductivity and heat dissipation, specific can be customized according to demand。
