Main properties and structure of 2 mm thick sheets and 20×100 mm extruded strips made under industrial conditions from Al-Cu-Mg heat-resistant B-1213 alloy with Ag, Cr, Mn and Zr additions were investigated. It was stated that wrought B-1213 alloy semiproducts are superior to analogous semis made of widely used commercial heat resistant AK4-1ch-type alloys (analogues - AU2GN, 2618 alloys) in strength properties and heat resistance characteristics (by 10-20 %) as well as in crack resistance and fatigue life (by 20-40 %). B-1213 alloy is intended for replacement of traditional heat-resistant alloys of system Al-Cu-Mg-Fe-Ni in advanced aircraft primary structure components subjected heating at elevated temperatures (up to 200-250 oC) and allows one to increase weight efficiency, service life and reliability.
