The corrosion resisting property of Mg-Li alloy is quite bad and the mechanical property is also bad, author prepared the Mg-9Li-1Zn alloy/Al cladding plate using cold-rolling. Author studied the technology of cold-rolling and the annealing system of Mg-9Li-1Zn alloy/Al cladding plate, and analyzed the recrystallization behavior of Mg-9Li-1Zn sheet for different annealing system, and tested the mechanical properties. The results showed that the critical reduction of Mg-9Li-1Zn alloy/Al cladding plate is about 50 percent, and the best reduction is about 60 approx 65 percent. After annealing alpha phases can obviously spheroidize, and the complete recrystallization occurs after annealing at 300 deg C for 3h, and at the same time the microstructure and properties of the composite plate are the best. The density of Mg-9Li-1Zn alloy/Al cladding plate is 1.6 approx 1.7g/cm~3, it still has the character of lightness, at the same time the corrosion resisting property can rise largely.
