| abstract |
The present invention relates to a magnesium alloy annealed material having excellent strength and excellent extrusion or rolling formability, and more specifically, 0.1 to 1.5% of group IIIa, 1.0 to 4.0% of group IIIb, optionally Group IIa and IVa in atomic%. The present invention relates to a magnesium alloy annealing material which is a two-phase composite structure composed of Mg and inevitable impurities by adding 0.35% or less of Group VIIa and IVb, alone or in a mixture, and the remainder of Mb and inevitable impurities.n n n In addition to the electromagnetic shielding ability of magnesium, the magnesium alloy annealed material of the present invention has light weight, high strength, high toughness, and high formability, and can be used in portable electronic products such as notebook computers, mobile phones, digital cameras, camcorders, CD players, PDAs, and MP3 players. It is suitable for automobile parts such as engine room bonnet, oil pan, door inner panel, and aircraft structural parts. |
