Abstract：The pursuit of higher-strength materials has always been the goal pursued by researchers in structural materials,
especially magnesium (Mg) alloys, which are lightweight structural materials known as “ the lightest structural alloy of the
21st century ” . Low-density, high-performance Mg alloys have become very attractive in various technical applications,
especially with the addition of major alloying elements in Mg alloys, which greatly enhance their strength and plasticity and
further promote the development of Mg alloys with different alloying systems. From this aspect, this review summarizes the
research and development status of cast Mg alloys and wrought Mg alloys. Highlights are reviewed from the perspectives of
alloying systems, alloy composition, preparation processes, and mechanical properties, aiming to provide a reference for the
future design of higher-strength Mg alloys with excellent overall properties.
