Abstract: Aluminum alloy has excellent elasticity, strength, and toughness. As a kind of high-strength alloy, 6061 aluminum alloy has excellent mechanical and processing properties, so it is widely used in the development of Chinese inverted arch arrows. In this paper, the effect of annealing temperature on the mechanical properties of 6061 aluminum alloy was studied. The microstructure, hardness, and tensile properties of the experimental aluminum alloy after different annealing temperatures were analyzed. The effect of annealing temperature on the microstructure, hardness, strength, elongation, and reduction of area of the alloy was clarified. It was found that when the annealing temperature is 580 °C, its mechanical properties are the best, making it more suitable for the development of Chinese inverted arch arrows.
