C50710-SH KLF7-SH銅合金品質保證
按材料形成方法劃分為可為鑄造銅合金和變形銅合金。事實上,許多銅合金既可以用于鑄造,又可以用于變形加工。通常變形銅合金可以用于鑄造,而許多鑄造銅合金卻不能進行鍛造、擠壓、深沖和拉拔等變形加工。鑄造銅合金和變形銅合金又可以細分為鑄造用紫銅、黃銅、青銅和白銅。
norms from Copper alloys
Please read below on the wished for trade-name in the left hand column, and get it translated into LM-language on the right-hand
column. The right hand column with our name is either identical in composition or a fully replaceable alloy with only minor
differences. The column in the middle states the norm and its country of origin.
With no marks in front of LM’s alloy = alloy is identical, with this sign “~” = alloy is very similar, fully replaceable.

電力輸送
力輸送中需要大量消耗高導電性的銅,主要用于動力電線電纜、匯流排、變壓器、開關、接插元件和聯(lián)接器等。
在電線電纜的輸電過程中,由于電阻發(fā)熱而白白浪費電能。從節(jié)能和經(jīng)濟的角度考慮,目前世界上正在推廣""zui佳電纜截面""標準。過去流行的標準,單純地從降低一次安裝投資的角度出發(fā),為了盡量減小電纜截面,以在設計要求的額定電流下,不至出現(xiàn)危險過熱,來確定電纜的zui低允許尺寸。按這種標準鋪設的電纜,雖然安裝費低了;但是在長期使用過程中,電阻能耗卻比較大。
