AA7050and AA2024 aluminum alloys used in aviation were jointed by friction stir welding, and the tensile properties and fracture surfaces were investigated. The results show that the ultimate strength and the yield limit of welded materials can reach 90% and 75% for AA7075and AA2024 respectively, while the ultimate strength of AA7050/AA2024 FSW can reach 60.5% of AA7050 and 70.8% of AA2024, the yield limit can reach 46.2 % of AA7050 and 75.5% of AA2024. The equiaxial fine grains were found in weld nugget, the coarsen and distorted grains in the thermo-mechanically affected zone, and coarse grains in heat affected zone. The fractures occur at the advancing side between thermo-mechanically affected zone and heat affected zone. Dimples appeared on the fracture surfaces means that the fracture is ductile fracture.
