工艺性能
播报编辑⑴成形性能①该合金热态工艺塑性良好。锻造和模锻温度为420~475°C,在此温度范围内进行变形率＞80%的热变形。②其冷冲压性能与合金状态有关,退火（O）状态的冷冲压性能良好,H32、H34状态时次之,而H36/H38状态时不好。⑵焊接性能①该合金的气焊、电弧焊、电阻焊、点焊、缝焊性能良好,二氩弧焊时出现结晶裂缝倾向。硬钎焊性能尚好,而软钎焊性能较差。②焊缝的强度和塑性高,焊缝强度达基体金属强度的90%~95%。但焊缝的气密性不高,推荐用5A03合金作焊料,可提高其气密性,并可消除裂缝倾向。⑶机械加工性能该合金退火状态的切削加工性能不好,而冷作硬化状态时有所改善。
应用
播报编辑是应用最广的一种防锈铝，这种合金的强度高，特别是具有抗疲劳强度：塑性与耐腐蚀性高，不能热处理强化，在半冷作硬化时塑性尚好，冷作硬化时塑性低，耐腐蚀好，焊接性良好，可切削性能不良，可抛光。用途主要用于要求高的可塑性和良好的焊接性，在液体或气体介质中工作的低载荷零件，如油箱，汽油或润滑油导管，各种液体容器和其他用深拉制作的小负荷零件：线材用来做铆钉。
