HIGHLY MOLDED MAGNESIUM ALLOY SHEET AND METHOD FOR MANUFACTURING SAME

Abstract:

The present invention relates to a high-formed magnesium alloy sheet and a method of manufacturing the same. One embodiment of the present invention provides a magnesium alloy sheet comprising: 3.0 wt % or less (excluding 0 wt %) of Zn, 1.5 wt % or less (excluding 0 wt %) of Ca, 1.0 wt % or less (excluding 0 wt %) of Mn, balance of Mg and inevitable impurities, for a total of 100 wt %, wherein, the magnesium alloy sheet further comprises 0.3 wt % or less of Al, based on 100 wt % of the entire magnesium alloy sheet, and the magnesium alloy sheet satisfies the following formulas (1) and (2): [Zn]/[Ca].ltoreq.4.0 formula (1) [Zn]+[Ca]>[Mn] formula (2) [Zn], [Ca], and [Mn] refer to weight percent of each component.
