Abstract

The invention provides a high-strength aluminum alloy material and a preparation method thereof. The high-strength aluminum alloy material is composed of the following components by weight percentage: 2.3-3.4% copper, 0.8-1.4% manganese, 0.5-1.0% iron, 0.2-0.4% cobalt, 0.03-0.06% calcium, 0.15-0.42% nickel, 0.5-0.8% titanium, 0.15-0.42% nickel, 0.25-0.51% zirconium, 0.1-0.3% Molybdenum, 0.08-0.2% scandium, 2.1-4.2% silicon. In the present invention, the strength and plasticity of the aluminum alloy material are improved by adding zirconium and molybdenum to the aluminum alloy material, and the addition of cobalt and scandium to the aluminum alloy material can effectively overcome casting cracks, improve the quality of the aluminum alloy, and improve the quality of the aluminum alloy product. Cost rate. According to the experimental results, the strength of aluminum alloy products is above 547MPa, the elongation rate is above 7.9%, and the qualified rate of flaw detection is above 99%.
