specific Embodiment approach 1
[0004] Specific Embodiment 1: In this embodiment, the aluminum alloy pre-stretched sheet for aviation is composed of 0.20 parts of Si, 0.30 parts of Fe, 1.7 parts of Cu, 0.10 parts of Mn, 0.22 parts of Cr, and 0.06 parts by weight. Made of Ti, 2.5 parts of Mg, 5.60 parts of Zn and the rest of Al, totaling 100 parts.
specific Embodiment approach 2
[0005] Specific embodiment two: the production method of aviation aluminum alloy pre-stretched plate in this embodiment is realized through the following steps: 1. According to the ratio of parts by weight, 0.20 parts of Si, 0.30 parts of Fe, 1.7 parts of Cu, 0.10 parts of Mn, 0.22 parts of Cr, 0.06 parts of Ti, 2.5 parts of Mg, 5.60 parts of Zn and the balance of Al were mixed to make a total of 100 parts. 2. Melt the mixed metal at 700-750°C for 5-12 hours, then cast the smelted metal at a temperature of 690-705°C and a casting speed of 55-60mm / min, and Cast the metal into an ingot with a cross-sectional size of 300×1200mm; 3. Soak the ingot at a temperature of 450-460°C for 40-42 hours, and then plan the soaked ingot in a conventional method according to actual needs Edge, sawing and milling; 4. At a temperature of 370-410°C, hot-roll the ingot according to the actual needs, and cut the length of the wool; 5. Put the straightened wool at 468-472°C. Quenching for 60 to 120 ...
specific Embodiment approach 3
[0006] Embodiment 3: The difference between this embodiment and Embodiment 2 is that in step 2, the mixed metals are smelted at 710-740° C. for 6-10 hours. Other steps are the same as in the second embodiment.
