進(jìn)口美鋁ALCOA7075鋁棒哪里有賣？ 正宗進(jìn)口美國(guó)ALCOA7075鋁棒經(jīng)銷商。
7075鋁棒簡(jiǎn)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(píng)估大氣風(fēng)化，應(yīng)力腐蝕開(kāi)裂和剝落在目前所有可用的脾氣。這些值已被用來(lái)作為較近期高的發(fā)展比較標(biāo)準(zhǔn)強(qiáng)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(dòng)類型）實(shí)力脾氣（T6）的。 ?
7075鋁棒許多熱處理和熱處理方法可用來(lái)譜載下的疲勞裂紋生長(zhǎng)行為正在成為日益重要的合金疲勞關(guān)鍵的選擇飛機(jī)結(jié)構(gòu)。各種高強(qiáng)度航天合金飛行小時(shí)的生活中使用兩種類型的預(yù)測(cè)相比，疲勞譜;機(jī)翼根應(yīng)用（張力為主），和水平尾翼的應(yīng)用（拉伸，壓縮）。制定最佳的強(qiáng)度，韌性和其他可取的字符符teristics合金正確應(yīng)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
