Abstract

The invention discloses a die casting aluminum alloy. The die casting aluminum alloy comprises following components including, by weight percent, 8.5% to 10.5% of Si, 2.2% to 4.2% of Cu, 0.15% to 0.25% of Mg, 0.5% to 0.8% of Zn, 0.2% to 0.8% of Fe, 0.1% to 0.3% of Mn, 0.1% to 0.3% of Ni, 0.1% to 0.2% of Sn, 1.5% to 2.5% of Sr, 0.05% to 0.08% of Ti, and the balance Al. Al-Si eutecticum formed by Si and Al in the die casting aluminum alloy has the good plasticity, added Mg and Mn can improve alloy mechanical strength, in addition, through the synergistic effect of Sr, Ti and the other elements, an aluminum alloy structure can be refined, the average size of grains of the all portions of the aluminum alloy structure can be small, distribution is uniform, and toughness and ductility are greatly improved.

Description

technical field [0001] The invention relates to a die-casting aluminum alloy. Background technique [0002] As people's requirements for lighter products become increasingly strong, aluminum alloys are getting more and more attention. Die-casting aluminum alloy has a great advantage in the simplicity of the process because it can realize one-time molding of complex structures, which makes the application of die-casting aluminum alloy very common. [0003] However, most of the existing die-casting aluminum alloys have problems of low mechanical strength, poor toughness, and low elongation, which greatly limit their application in structures, and thus urgently need to be solved. Contents of the invention [0004] The purpose of the present invention is to address the above problems and provide a die-casting aluminum alloy to solve the problems of low mechanical strength, poor toughness and low elongation of the existing die-casting aluminum alloys. [0005] The purpose of ...
