是2468 20 #一年前做好的线,现在一端打端子一端渡锡插板,焊好板后一拉,线芯就从中间断了,有氧化了的白色粉末。线还能用吗。
最先公司不懂,买了 很多铜包铝,现在还有。还能用吗

悲剧 多长时间就氧化了捏??铜包铝很脆,而且也容易氧化,你最好还是不要用了。
CCA工艺不佳.

铜包铝也不是一无是处啊!总归各有所需吗,它存在就有它存在的价值
铜包铝并不是一无是处,但是要符合标准要求的,用在一些信号,如网络线等。
但是很多厂商,为了节约成本,用电镀的,更严重是,只有表面颜色是铜色,这样子做品质就无法保证了。
CCA材质. 1, 本身无错.
2, 铜皮被偷工减料. < 15%.
3, 加工工艺不佳.
4, 误用 CCA 的特性.
