Abstract: PURPOSE: A method for manufacturing a magnesium alloy sheet and a magnesium alloy sheet manufactured by the same are provided to improve tensile strength compared with a magnesium alloy sheet formed by a conventional ingot casting method. CONSTITUTION: A method for manufacturing a magnesium alloy sheet comprises following steps. Molten metal is formed by dissolving magnesium and calcium to have the content of the calcium which is 0.5 weight%-5 weight% compared with the whole molten content. The molten metal is maintained from the temperature, in which liquid fraction is 70%, to the temperature, in which molten metal is ignited, and is transferred to a nozzle at the same time. The molten metal is injected from the nozzle between two cooling rolls(S300). A magnesium alloy sheet is formed.
