The invention belongs to the field of chemical materials and particularly relates to an aluminum
alloy material, a preparation method and application of the aluminum
alloy material in a
solar energy photovoltaic support. The aluminum
alloy material is composed of the following components of, by
mass, 0.2%-0.4% of Si, 0.08%-0.20% of Cu, 0.6%-0.8% of Mg, 0.15%-0.25% of Zr, 0.15%-0.25% of Ti, 0.01%-0.15% of Mn and the balance aluminum and inevitable impurities. According to the designed aluminum alloy material, by adding
metal elements of Si, Cu, Mg, Zr, Ti, Mn and the like, the grain refinementdegree is improved by a large margin, and the effect in the aspect of promoting the comprehensive properties such as tensile strength, the elongation and the
corrosion-resistant property of the aluminum alloy material is significant. The aluminum alloy material is used for preparing a
solar energy photovoltaic support profile, so that the
corrosion-resistant property of the photovoltaic support prepared from the aluminum alloy material is better than that of a traditional aluminum alloy photovoltaic support component.
