Title
(DE) BLECH AUS MAGNESIUMLEGIERUNG UND VERFAHREN ZUR HERSTELLUNG DAVON
(EN) MAGNESIUM ALLOY SHEET AND METHOD FOR MANUFACTURING SAME
(FR) TÔLE D'ALLIAGE DE MAGNÉSIUM ET SON PROCÉDÉ DE FABRICATION
Abstract
(EN) An exemplary embodiment of the present invention relates to a magnesium alloy sheet and a manufacturing method thereof. The exemplary embodiment of the present invention provides a magnesium alloy sheet including 0.5 to 2.1 wt% of Al, 0.5 to 1.5 wt% of Zn, 0.1 to 1.0 wt% of Ca, and a balance of Mg and inevitable impurities, with respect to a total of 100 wt% of the magnesium alloy sheet.
(FR) La présente invention concerne une tôle d’alliage de magnésium et son procédé de fabrication. L’un mode de réalisation de la présente invention concerne une tôle d'alliage de magnésium comprenant, par rapport à un total de 100 % en masse de la tôle d’alliage de magnésium : 0,5 à 2,1 % en masse d’Al ; 0,5 à 1,5 % en masse de Zn ; 0,1 à 1,0 % en masse de Ca ; et le reste étant constitué de Mg et des impuretés inévitables.
