ZL111合金是以铝－硅系为基础，并添加铜和镁合金元素，通过其对铝基体的固溶强化和第二相（CuAl2 Mg2 Si和W相）强化，来达到提高室温强度和高温强度的目的，同时加入少量钛来细化晶粒，并加入一定量的锰来消除杂质铁的有害影响。该种合金有良好的熔铸工艺性，气密性高，热裂倾向和线收缩小。其工艺性能和热强性达到了国外同类型新型合金的水平。
The ZL111 alloy is take the aluminum - silicon department as a foundation, and the increase copper and the magnesium alloy element, (CuAl2 Mg2 Si and W) strengthen through it to the aluminum substrate melting strengthening and the two phase, achieved enhances the room temperature intensity and the strength at high temperatures goal, simultaneously joins the few titanium to come the thin crystal grain, and joins a quota the manganese to eliminate the impurity iron the harmful influence. This kind of alloy has the good casting technology capability, gas tightness is high, the thermal crack tendency and the line contract slightly. Its shop characteristics and were hot have achieved the overseas similar new alloy level .
