    7系鋁合金是另外一種常用的合金,品種繁多.它包含有鋅和鎂.比較常見的鋁合金中強度較好的就是7075合金,但是它無法進行焊接,而且它的抗腐蝕性相當差,很多CNC切削制造的零部件用的就是7075合金.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,到達非常高度度特性。這系列材料一般都加入少量的銅、鉻等合金,而其中以編號7075鋁合金尤為上品,強度較高,適合飛機構架及高 強度配件。

    7系鋁合金屬Al-Zn-Mg-Cu系超硬鋁,該合金是20世紀40年代末期就已應用于飛機制造業,至今仍在航空工業上得到廣泛應用的非常高度度變形鋁合金。其特點是,固溶處理后塑性好,熱處理強化效果特別好,在150℃以下有高的強度,并且有特別好的低溫強度;焊接性能差;有應力腐蝕開裂傾向;需經包鋁或其他保護處理使用。雙級時效可提高合金抗應力腐蝕開裂的能力。在退火和剛淬火狀態下的塑性稍低于同樣狀態的2A12.稍優于7A04,板材的靜疲勞.缺口敏感,應力腐蝕性能優于7A04.密度為2.75

    狀態代號
    范圍
    本標準規定了變形鋁合金的狀態代號。

    本標準適用于鋁及鋁加工產品。

    基本原則
    2.1基礎狀態代號用一個英文大寫字母表示。 2.2細分狀態代號采用基礎狀態代號后跟一位或多位阿拉伯數字表示。 2.3基本狀態代號 基本狀態分為5種 代號 名稱 說明與應用 F 自由加工狀態 適用于在成型過程中,對于加工硬化和熱處理條件無特殊要求的產品,該狀態產品的力學性能不作規定。 O 退火狀態 適用于經完全退火獲得較低強度的加工產品。 H 加工硬化狀態 適用于通過加工硬化提高度度的產品,產品在加工硬化后可經過(也可不經過)使強度有所降低的附加熱處理。 W 固熔熱處理狀態 處理狀態 一種不穩定狀態,僅適用于經固溶熱處理后,室溫下自然時效的合金,該狀態代號僅表示產品處于自然時效階段。 T 熱處理狀態(不同于F、O、H狀態) 適用于熱處理后,經過(或不經過)加工硬化達到穩定的產品。T代號后面必須跟有一位或多位阿拉伯數字。在T字后面的靠前位數字表示熱處理基本類型(從1~10),其后各位數字表示在熱處理細節方面有所變化。如 6061-T 62 ;5083-H 343等。 T1-從成型溫度冷卻并自然時效至大體穩定狀態。 T2-退火狀態(只用于鑄件)。 T3-固溶處理冷作后自然時效。 T31-固溶處理冷作(1%)后自然時效。 T36-固溶處理冷作(6%)后自然時效。 T37-固溶處理冷作(7%)后自然時效,用于2219合金。 T4-固溶處理后自然時效。 T41-固溶處理后沸水淬火。 T411-固溶處理后空冷至室溫,硬度在O及T6之間,殘余應力低。 T42-固溶處理后自然時效。由用戶進行處理,適于2024合金,強度比T4稍低。 T5-從成型溫度冷卻后人工時效。 T6-固溶處理后人工時效。 T61-T41+人工時效。 T611-固溶處理,沸水淬火。 T62-固溶處理后人工時效。 T7-固溶處理后穩定化。提高尺寸穩定性,減小殘余應力,提高抗蝕性。 T72-固溶處理后過時效。 T73-固溶處理后進行分級時效,強度比T6低,抗蝕性顯著提高。 T76-固溶處理后進行分級時效。 T8-固溶處理冷作后人工時效。 T81-固溶處理后冷作,人工時效。為改善固溶處理后的變形及改善強度。 T86-固溶處理后冷作(6%),人工時效。 T87-T37+人工時效。 T9-固溶處理后人工時效再冷作。 T10-從成型溫度冷卻,人工時效后冷作。 Tx51-為清理固溶處理后的殘余應力進行拉伸處理。 板材0.5~3%的較久變形,棒、型材1~3%的較久變形。 X代表3、4、6或8,例如T351、T451、T651、T851,適用于板、拉制棒、線材,拉伸清理應力后不作任何矯正而時效。T3510、T4510、T8510,適用于擠壓型材,拉伸清理應力后為使平直度符合公差進行矯正,并時效。 Tx52-為清理固溶處理后的殘余應力進行壓縮變形,固溶處理后進行2.5%的塑性變形然后時效,例如T352、T652。 Tx53-清理熱應力。 Tx54-為清理準確鍛件固溶處理后的殘余應力進行壓縮變形。

    (1)組合之元素性質以較高百分率表示,除非列出的是一個范圍或是較低值。

    (2) 為了定出合適的數值限制,分析得來的觀察或計算數值都是依據標準規則(ANSI Z25.1)

    以表示明確的范圍。

    (3) 除了非合金外,合金內的元素所規定的份量通常在分析報告中指示出來。但如果在分析 過程中

    懷疑有其它元素存在或有部份元素被懷疑有過量的情形,更應進一步的分析直至有證實為止。

    (4) 不是經由精煉過程的非合金鋁中的鋁質的含量就是其它的金屬的總量和高標準純鋁之差-其差別

    在于百份0.01或稍多一點。(百份比的小數點后第二位)

    (5) 較多可含有0.25%鋯和鈦。

    鋅是7075中主要合金元素,向含3%-7.5%鋅的合金中添加鎂,可形成強化效果顯著的MgZn2,使該合金的熱處理效果遠遠勝過于鋁-鋅二元合金。提高合金中的鋅、鎂含量,抗拉強度會得到進一步的提高,但其抗應力腐蝕和抗剝落腐蝕的能力會隨之下降。經受熱處理,能到達非常高的強度特性。

    7075材料一般都加入少量銅、鉻等合金,該系當中以7075-T651鋁合金尤為上品,被譽為鋁合金中較優良的產品,強度高、遠勝任何軟鋼。此合金并具有良好機械性及陽較反應。代表用途有航空航天、模具加工、機械設備、工裝夾具,特別用于制造飛機結構及其他要求強度高、抗腐蝕性能強的高應力結構體。
