Document Type and Number:
WIPO Patent Application WO/2020/067704
Kind Code:
A1
Abstract:
The present invention relates to a magnesium alloy sheet, which comprises, on the basis of 100 wt% of an entire magnesium alloy sheet, 0.1-1.5 wt% of Zn, 0.08-0.7 wt% of Gd, and the balance of Mg and other inevitable impurities, and satisfies the following relation 1. [Relation 1] [Zn]/[Gd] ≥ 3.0 (wherein [Zn] and [Gd] means wt% of a corresponding element.)
