With 0.50\u20131.1% magnesium as the primary alloying element, it offers excellent weldability and formability while keeping costs lower than higher-Mg 5xxx alloys such as 5052 or 5083. Its thermal conductivity of ~200 W\/m\u00b7K and electrical conductivity of ~50\u201352% IACS make it suitable for architectural panels, signage, appliance trim, and electrical components.
