NOVEL WELDABLE ANTI-CORROSIVE ALUMINIUM-MAGNESIUM ALLOY CONTAINING A HIGH AMOUNT OF MAGNESIUM, ESPECIALLY FOR USE IN AUTOMOBILES

摘要

A novel weldable aluminum-magnesium alloy comprising at least 5-6 wt. % magnesium (Mg), 0.05-0.15 wt. % zirconium (Zr), 0.07-1 wt. % manganese (Mn), 0.01-0.02 wt. % titanium (Ti), at least 0.005 wt. % cerium (Ce), 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, in addition to aluminium (Al) and unavoidable impurities with a maximum of 0.2 wt. % silicon (Si).
