2×××系铝铜合金,,,,,,,,,,,,,,,

标准：GB/T3190-1996,,,,,,,,,,,,,,,

特性及适用范围：,,,,,,,,,,,,,,,

2XXX系列为铝－铜－镁系中的典型硬铝合金，其成份比较合理，综合性能较好。很多国家都生产这个合金，是硬铝中用量最大的。该合金的特点是：强度高，有一定的耐热性，可用作150°C以下的工作零件。温度高于125°C，2XXX系列合金的强度比7075合金的还高。热状态、退火和新淬火状态下成形性能都比较好，热处理强化效果显著，但热处理工艺要求严格。抗蚀性较差，但用纯铝包覆可以得到有效保护;焊接时易产生裂纹，但采用特殊工艺可以焊接，也可以铆接。广泛用于飞机结构、铆钉、卡车轮毂、螺旋桨元件及其他种种结构件。

6×××系铝硅合金,,,,,,,,,,,,,,,

标准：GB/T3190-1996,,,,,,,,,,,,,,,

特性及适用范围：,,,,,,,,,,,,,,,

,,,,,,,,,,,,,,,

6XXX系列属热处理可强化合金，具有良好的可成型性、可焊接性、可机加工性和，同时具有中等强度，在退火后仍能维持较好的操作性.,,,,,,,,,,,,,,,

6XXX系列合金的主要合金元素是镁与硅AlMgSi1Cu，并形成Mg2Si相。若含有一定量的锰与铬，可以中和铁的坏作用；有时还添加少量的铜或锌，以提高合金的强度，而又不使其抗蚀性有明显降低；导电材料中还有少量的铜，以抵销钛及铁对导电性的不良影响；锆或钛能细化晶粒与控制再结晶组织；为了改善可切削性能，可加入铅与铋。在Mg2Si固溶于铝中，使合金有人工时效硬化功能。,,,,,,,,,,,,,,,

6061-T651是6XXX系列合金中主要合金，是经热处理预拉伸工艺生产的高品质铝合金产品，其强度虽不能与2XXX系或7XXX系相比，但其镁、硅合金特性多，具有加工性能极佳、优良的焊接特点及电镀性、良好的抗腐蚀性、韧性高及加工后不变形、材料致密无缺陷及易于抛光、上色膜容易、氧化效果极佳等优良特点。,,,,,,,,,,,,,,,

7×××系铝锌合金,,,,,,,,,,,,,,,

标准：GB/T3190-1996,,,,,,,,,,,,,,,

特性及适用范围：,,,,,,,,,,,,,,,

①７０００铝合金是另外一种常用的合金，品种繁多．它包含有锌和镁．比较常见的铝合金中强度最好的就是７０７５合金，但是它无法进行焊接，而且它的抗腐蚀性相当差，很多ＣＮＣ切削制造的零部件用的就是７0７５合金．锌在这系列中是主要合金元素，加上少许镁合金可使材料能受热处理，到达非常高强度特性。这系列材料一般都加入少量的铜、铬等合金，而其中以编号7075铝合金尤为上品，强度最高，适合飞机构架及高强度配件。,,,,,,,,,,,,,,,

②7075属Al-Zn-Mg-Cu系超硬铝，该合金是20世纪40年代末期就已应用于飞机制造业，至今仍在航空工业上得到广泛应用的超高强度变形铝合金。其特点是，固溶处理后塑性好，热处理强化效果特别好，在150℃以下有高的强度，并且有特别好的低温强度；焊接性能差；有应力腐蚀开裂倾向；需经包铝或其他保护处理使用。双级时效可提高合金抗应力腐蚀开裂的能力。在退火和刚淬火状态下的塑性稍低于同样状态的2A12.稍优于7A04，板材的静疲劳.缺口敏感，应力腐蚀性能优于7A04。,,,,,,,,,,,,,,,
