Abstract： The research status of influence of scandium on microstructure and properties of aluminum alloy was reviewed. Sc can refine the grain size of aluminum alloy and inhibit recrystallization, which had an important influence on the improvement of mechanical properties, welding properties and corrosion resistance. Combined with the research at home and abroad, the research and future application of Sc modified aluminum alloy are prospected.
