Abstract

A weldable, corrosion resistant aluminum-magnesium alloy consisting essentially of 3 to 5% by weight magnesium (Mg), 0.05 to 0.15% by weight zirconium (Zr), 0.05 to 0.12% by weight manganese (Mn), 0.01 to 0.2% by weight titanium (Ti), 0.05 to 0.5% by weight of one or more elements selected from the scandium group of the Periodic Table and/or terbium (Tb), wherein at least 0.15% by weight scandium (Sc) is included with or without terbium (Tb) and with or without 0.05 to 0.35% by weight of one or more elements from the lanthanide series, the balance being aluminum (Al), and unavoidable contaminants not exceeding 0.2% by weight silicon (Si).
