5.11.2 銅

Both as an alloying element in alloys such as steels and aluminum and as a base for copper alloys,

copper is a very valuable metal.

兩者都如一種使元素成合金在合金如此的當做鋼和鋁而且如銅合金的基礎,銅是非常有價值的金屬。

included in the copper-based alloys are brass

(copper and zinc),bronze(copperand tin),cupronickel(copper and nickel),leaded cop-

per,leaded brass,aluminum bronzes,nickel silver(copper,nickel,and zinc),and high cop-

per.

包含在以銅為基礎的合金之中是黃銅 (銅和鋅) 、青銅 (銅和錫), 銅鎳合金(銅和鎳),一般的銅

,一般銅、鋁青銅,鎳銀 (銅、鎳和鋅) 、和高的銅。

Table 5-3 shows that copper and its alloys are processed easily by most common meth-ods,

except certain types of welding.Several systems of designation exist for copper and

its greatest value as an electrical conductor.

表5-3 表示, 銅和其他合金由多數共同的方法容易地處理, 除了某些類型銲接。

High purity of over 99.9% is sought to attain

the best conductivity and formability.

指定幾個系統為銅和它最了不起的價值存在作為一個電子指揮。 高純度99.9%尋求獲得最佳的傳導性和可成形性。

Due to its scarcity and weight, the trend is, when

possible, to move away from copper as electrical conductors.

由於它的缺乏和重量, 趨向是, 當可能, 從銅行動作為電子指揮時。

Copper and copper alloys de-

velop a protective film that will not corrode in water or nonoxidizing acids.

銅和銅合金發展將不在水或非氧酸中使腐蝕的一個保護的影片。

it will corrode

if liquids, solids, or gases break down the protective film or if other conditions cause elec-

trolysis to develop.

如果液體、固體或瓦斯損壞保護的影片或其他的情況導致電分解發展,它將使腐蝕。

    5.11.2 銅

    Both as an alloying element in alloys such as steels and aluminum and as a base for copper alloys,

    copper is a very valuable metal.

    ( Both … and ….. 是一個句型 ,這樣看整句就很清楚了,第一個as 及第三個as 很對稱,在這裡有 “ 當做,用為,做為”的意思。)

    做為一種合金元素於 合金中諸如 鋼 和 鋁,及做為銅合金的基礎兩者,銅是一種 非 常 有 價 值 的 金 屬 。

    included in the copper-based alloys are brass

    (copper and zinc),bronze (copper and tin),cupronickel(copper and nickel),leaded copper,leaded brass,aluminum bronzes,nickel silver(copper,nickel,and zinc),and high copper.

    ( 這裡有許多銅合金專業名詞, 可參考下列網站,http://www.copper.org/resources/properties/microst... ,copper 有時有人稱為“紅銅” , nickel silver 也有人稱為“洋銀” ,

    high copper則 ???? )

    包含在以銅為基礎的合金之中是黃銅 (銅和鋅) 、青銅 (銅和錫), 白銅 (銅 和 鎳 ),含鉛銅 , 含鉛黃銅、鋁青銅 ,鎳銀 (銅、鎳和 鋅 ) 、和高的銅。

    Table 5-3 shows that copper and its alloys are processed easily by most common methods , except certain types of welding.

    表5-3 顯示 除了某 些 銲 接 類型外,銅 和 銅 合 金 經由 多數一般方法很容易處理,。

    Several systems of designation exist for copper and

    its greatest value as an electrical conductor.

    因銅及它做為電子導體的極高價值幾個因銅命名的系統存在著。

    High purity of over 99.9% is sought to attain

    the best conductivity and formability.

    99.9%以上的高純度被找來以獲得最佳的傳導性和可成形性。

    Due to its scarcity and weight, the trend is, when

    possible, to move away from copper as electrical conductors.

    由於它的稀有和重量, 趨勢是, 當可能 的話, 不把銅用為電子導體。

    Copper and copper alloys develop a protective film that will not corrode in water or nonoxidizing acids.

    (develop 有發展 ,形成 的意思 , 這裡譯“形成”會比較通順 , film 有影片, 軟片,薄膜的意思, 這裡譯“薄膜” 較通順 )

    銅及它的合金 形成一個在水或非氧酸中不腐蝕的保護薄膜。

    it will corrode if liquids, solids, or gases break down the protective film or if other conditions cause electrolysis to develop.

    如果液體 、固體或氣體破壞這個保護薄膜或其他的情況引起電分解形成 ,它將腐蝕。

    I learned something about copper and copper alloy from your artical, it is very interesting, thanks.
