Embodiment 1
[0055] Aluminum alloys were prepared as follows:
[0056]Batching, smelting, composition adjustment, melt purification, grain refinement, casting, sawing, milling, rolling, packaging, delivery (user), slitting, capping and anodizing are carried out in sequence;
[0057] In the batching process, the mass content of Si is controlled to be ≤0.10%, and the mass content of Fe is ≤0.18wt%;
[0058] During the smelting process, the alloy raw materials were sampled and analyzed after melting, and the mass content of the Ti element was adjusted to 0.005%; the temperature of the furnace refining was 730°C, and the time of the furnace refining was 15 minutes; the refining gas of the online degassing and refining It is argon, the temperature of online degassing and refining is 720°C, and the temperature of online filtration is 710°C; the mass content of Ti element in front of the furnace is controlled at 0.005%; Produce alloys with low content of Fe and Ti elements, and appropriately red...
