';font-family:calibri;mso-fareast-font-family:宋体;>
C50715(KLF5)是在电解铜中加入了少量的Fe，P以及Sn的铜合金材料。';font-family:宋体;mso-ascii-font-family:calibri;>
';font-family:宋体;mso-ascii-font-family:calibri;>
属于热轧低锡合金的青铜，Fe-P化合物析出相比磷青铜具有更高的强度，';font-family:宋体;mso-ascii-font-family:calibri;>
';font-family:宋体;mso-ascii-font-family:calibri;>
更高的导电率，属于高成本的低锡青铜的改良材料';font-family:宋体;mso-ascii-font-family:calibri;>。
