The samples with 100 mm×150 mm of commercial aluminum alloys including ZL101A
ZL201A
2A50
2A14
2A12and 7A04were prepared by squeezing casting to analyze microstructures and mechanical properties.The results show that all these alloys prepared by squeeze castings exhibit fine grain structure
and the tensile-ruptured samples are characterized by the plastic fracture mode.The mechanical properties of ZL101A
