large;">适用范围</span></span></h3> <span quot;font-size: large;">　　②5083属于Al-Mg-Si系合金,使用范围广泛,特别是建筑业离不开此合金，是较有前途的合金。耐蚀性好，焊接性优良，冷加工性较好，并具有中等强度。5083的主要合金元素为镁，具有良好的成形加工性能、抗蚀性、焊接性，中等强度，用于制造飞机油箱、油管、以及交通车辆、船舶的钣金件，仪表、街灯支架与铆钉、五金制品、电器外壳等。 ③ AL-Mn系合金，是应用较广的一种防锈铝，这种合金的强度高，特别是具有舒缓劳累强度：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，如邮箱，汽油或润滑油导管。 </span> <h3 class="headline-2"><a></a><span
