是2468 20 #一年前做好的線,現(xiàn)在一端打端子一端渡錫插板,焊好板后一拉,線芯就從中間斷了,有氧化了的白色粉末。線還能用嗎。
最先公司不懂,買了 很多銅包鋁,現(xiàn)在還有。還能用嗎

悲劇 多長(zhǎng)時(shí)間就氧化了捏??10
銅包鋁很脆,而且也容易氧化,你最好還是不要用了。
11
CCA工藝不佳.

銅包鋁也不是一無是處。】倸w各有所需嗎,它存在就有它存在的價(jià)值
18
銅包鋁并不是一無是處,但是要符合標(biāo)準(zhǔn)要求的,用在一些信號(hào),如網(wǎng)絡(luò)線等。
但是很多廠商,為了節(jié)約成本,用電鍍的,更嚴(yán)重是,只有表面顏色是銅色,這樣子做品質(zhì)就無法保證了。
19
CCA材質(zhì). 1, 本身無錯(cuò).
2, 銅皮被偷工減料. < 15%.
3, 加工工藝不佳.
4, 誤用 CCA 的特性.
