2xxx (θ-Al2Cu, S-Al2CuMg, N-Al7Cu2Fe, Mg2Si), 5xxx (Mg2Si, Al6(Fe, Mn)), 6xxx (Mg2Si, S-Al2CuMg, Al6(Fe, Mn)), and 7xxx (Al3Fe, Al23Fe4Cu, Mg2Si) Al alloys. Excluding the micro-scale secondary phases, the 5xxx Al alloys also contain β-Al3Mg2 and 7xxx Al alloys have η-MgZn2 phase. The length of bars is 2 μm.
