7075鋁棒簡介，AA7075鋁棒用途，AL7075鋁棒產(chǎn)自美鋁 7075鋁棒耐腐蝕鋁合金7075已被徹底評估大氣風化，應力腐蝕開裂和剝落在目前所有可用的脾氣。這些值已被用來作為較近期高的發(fā)展比較標準強度航天合金。在7XXX系列合金，抵抗一般攻擊，SCC和剝落腐蝕的改善與高峰期相比，顯著超齡的脾氣（T7啟動類型）實力脾氣（T6）的。 7075鋁棒許多熱處理和熱處理方法可用來譜載下的疲勞裂紋生長行為正在成為日益重要的合金疲勞關鍵的選擇飛機結構。各種高強度航天合金飛行小時的生活中使用兩種類型的預測相比，疲勞譜;機翼根應用（張力為主），和水平尾翼的應用（拉伸，壓縮）。制定最佳的強度，韌性和其他可取的字符符teristics合金正確應用7075薄板和厚板產(chǎn)品。參照MIL-H6088，鋁熱處理合金附加信息。
Alloy 7075 has been thoroughly evaluated for corrosion resistance，of atmospheric weathering, stress-corrosion cracking and exfoliation，in all currently available tempers. These values have been used as a standard for comparison in the development of more recent high strength aerospace alloys. Within the 7XXX series of alloys,resistance to general corrosion attack, SCC and exfoliation improves significantly in the overage tempers (T7 type) compared with peak strength tempers (T6).
Fatigue crack growth behavior under spectrum loading is becoming increasingly important in the selection of alloys for fatigue critical aircraft structures. Various high strength aerospace alloys are compared for life prediction in flight hours using two types of fatigue spectrums; a wing root application (tension dominated), and a horizontal tail application (tension-compression). develop optimum strength, toughness and other desirable charac- teristics for proper application of alloy 7075 sheet and plate products. Refer to MIL-H-6088, Heat Treatment of Aluminum Alloys for additional information.
 Alloy 7075 sheet and plate products have application throughout aircraft and aerospace structures where a combination of high strength with moderate toughness and corrosion resistance are required.
Typical applications are alclad skin sheet, structural plate components up to 4 inches in thickness and general aluminum aerospace applications.
Note: value maximum if range not shown.
