Russian patent RU2287600 announced a new type of heat-resistant Al alloy deformation. The main alloying element contained in the alloy is in the range of (mass fraction): Cu 1.2% -2.4%, Mn 1.2% -2.2%, Zr 0.15% -0.6%, V 0.01% -0.15%, Sc 0.01% -0.2 %, The rest is Al. Microstructure is mainly composed of aluminum solid solution and secondary aluminide composition, the equilibrium solid line temperature of not less than 600 ℃, Vickers hardness of not less than 85HV. The ingot of the alloy can be rolled into a sheet and the slab heating temperature does not exceed 410 ° C. When the alloy is annealed at 290-410 ℃ for 1 ~ 20 h, the ultimate tensile strength is not less than 300 MPa (room temperature) and the strength at 100 ℃ for more than 30 MPa at 350 ℃.
