7075鋁線屬Al-Zn-Mg-Cu系超硬鋁,7075合金是20世紀40年代末期就已應用于飛機制造業(yè),至今仍在航空工業(yè)上得到廣泛應用的超高強度變形鋁合金。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(jīng)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(tài)下的塑性稍低于同樣狀態(tài)的2A12.稍優(yōu)于7A04,板材的靜疲勞.缺口敏感,應力腐蝕性能優(yōu)于7A04,其中以7075-T651狀態(tài)尤為上品,被譽為鋁合金中最優(yōu)良的產(chǎn)品,強度高,遠勝于軟鋼。此合金具有良好的機械性能及陽極反應,是典型的航空航天用鋁合金材料。
