7000系列鋁合金材料
鋅在這系列中是主要合金元素,加上少許鎂合金可使材料能受熱處理,到達(dá)非常高強(qiáng)度特性。
這系列材料一般都加入少量的銅、鉻等合金,而其中以編號(hào)7075鋁合金尤為上品,強(qiáng)度最高,
適合飛機(jī)構(gòu)架及高 強(qiáng)度配件。

註:
(1)組合之元素性質(zhì)以最高百分率表示,除非列出的是一個(gè)範(fàn)圍或是最低值。
(2) 為了定出合適的數(shù)值限制,分析得來的觀察或計(jì)算數(shù)值都是依據(jù)標(biāo)準(zhǔn)規(guī)則(ANSI Z25.1)
以表示明確的範(fàn)圍。
(3) 除了非合金外,合金內(nèi)的元素所規(guī)定的份量通常在分析報(bào)告中指示出來。但如果在分析 過程中
懷疑有其他元素存在或有部份元素被懷疑有過量的情形,更應(yīng)進(jìn)一步的分析直至有證實(shí)為止。
(4) 不是經(jīng)由精鍊過程的非合金鋁中的鋁質(zhì)的含量就是其他的金屬的總量和百分百純鋁之差-其差別
在於百份0.01或稍多一點(diǎn)。(百份比的小數(shù)點(diǎn)後第二位)
(22) 最多可含有0.25%鋯和鈦。
