铝合金的特点及应用

铝合金的密度比较小,由于铝的表面容易被氧化而形成一层致密的氧化铝薄膜,所以耐蚀性很好。由于铝的融化温度低,流动性好,易于制造各种复杂外形的零件,说明铝的铸造性能比较好。铝中加入一种或者多种元素后就会构成铝合金。铝合金比纯铝的强度和硬度都要好,有些铝合金还能经过热处理强化,强度胜过某些合金钢。铝合金保持了铝质量轻的特点,但是它的机械性能比铝要高的多。铝合金材料的应用可以作为受力构件,也可以作为门窗等材料,还能作为装饰和绝热材料。

铝合金的特点及应用

铝合金在铁路运输上的优点显著,主要特点是:节能消耗量低,质量轻等特点符合绿色环保的理念。在强度和刚性上完全满足安全的要求,使用铝合金可以大大减轻机车车辆的自重,一般说铝合金制成的车比钢材料制成的车重量要轻百分之四十,要想让高速列车更轻便,就要合理的搭配一下铝含量在它身上的配比。第二方面,铝合金的耐腐蚀性能好。铝和金表面形成了一层致密的氧化膜,在大气中具有良好的抗氧化能力。因此用铝合金制成的车比钢制成的车有更好的耐腐蚀性作用,在另一方面,铝合金的上色比较容易,在表面上一层漆进行喷涂也有效的预防腐蚀的作用。第三面铝合金材料在加工制造、维修方面比较简单。相对于其他材料来说没有那么复杂。铝合金材料能够适用于各种表面处理,不需要除锈处理,便于维修,给车辆在后期的维修中带来很多方便。
