銅在這系列中是主要金屬元素。這材料要經(jīng)固溶熱處理才得到一個(gè)適中的特質(zhì);
而在熱處理情況下其機(jī)械性能表現(xiàn)相等於或有時(shí)會(huì)超過(guò)低炭鋼所表現(xiàn)的。在需要
時(shí),材料可作人工陳化處理而增加其屈服強(qiáng)度,雖損失些金屬延展性,但對(duì)其拉
力強(qiáng)度並沒(méi)有多大影響。
2000系列合金材料並不比其它系列鋁合金料有較好的抗腐性,而在某些環(huán)境下,
亦可能會(huì)發(fā)生材料晶格之間腐蝕現(xiàn)象。所以這類合金在薄片情況下多加壓上一層
高純度合金或6000系列其中一種鎂合金來(lái)防止其電化學(xué)腐蝕反應(yīng)。在2000系列之
中,2024鋁合金料或可以說(shuō)是最為人所熟識(shí)及廣泛被接納為飛機(jī)選用金屬材 料。

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(lái)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(lái)。但如果在分析過(guò)程中懷疑有其他元素存在或有部份元素被懷疑有過(guò)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(guò)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)
