Weldable, corrosion-resistant, high-magnesium aluminum-magnesium alloy, especially for aerospace applications

摘要

A weldable anti-corrosive aluminium-magnesium alloy containing a high amount of magnesium comprising at least 5-6 wt. % magnesium (Mg), 0.05-0.15 wt. % zirconium (Zr), 0.05-0.12 wt. % manganese (Mn), 0.01-0.2 wt. % titanium (Ti), 0.05-0.5 wt. % of one or several elements from the scandium group and/or terbium (Tb), whereby at least scandium (Sc) is contained, 0.1-0.2 wt. % copper (Cu) and/or 0.1-0.4 wt. % zinc (Zn) in addition to aluminium (Al) and unavoidable impurities with a maximum of 0.1 wt. % silicon.
