2618合金属于Al-Cu-Mg-Fe-Ni可热处理强化合金,它是在Al-Cu-Mg系硬铝合金基础上加Ni、Fe、Si形成的,由于合金中加入了等量的Fe、Ni元素,生成大量的Al9FeNi难溶相。Al9FeNi相是硬脆的化合物,主要对高温下合金的变形起阻碍作用,经锻造和热处理后弥散分布于组织中,因而该合金是传统锻造合金中耐热性zui好的一种合金,使用温度200~250℃。冷热加工性能较,,焊接性能适中,适用于制造较高温度下使用的零件,如压气机叶轮、鼓风机叶轮、汽车用涡轮增压器等。
The 2618 alloy belongs to the Al-Cu-Mg-Fe-Ni heat treatable strengthening alloy, which is formed by adding Ni、Fe、Si on the basis of Al-Cu-Mg hard aluminum alloy, which produces a large amount of Al9FeNi insoluble phase due to the addition of an equal amount of Fe、Ni elements to the alloy. Al9FeNi phase is a hard and brittle compound, which mainly hinders the deformation of the alloy at high temperature. After forging and heat treatment, the alloy is dispersed in the structure, so the alloy is the best heat resistant alloy in the traditional forging alloy, using a temperature of 200~250℃. Heat and cold processing performance is better, weldability is better Medium, suitable for manufacturing parts used at higher temperature, such as compressor impeller, blower impeller, turbocharger for automobile, etc.
