Aluminium alloy radiator fin material

The invention provides an aluminium alloy radiator fin material. The problems that a conventional aluminium alloy radiator fin material processed through adopting the traditional 3003 aluminium alloy is low in strength and poor in anti-collapsing performance can be effectively solved, the material thickness can be greatly decreased, the cost of raw materials is reduced, the radiator can be protected from being corroded, and the service life of the integral radiator is prolonged. The aluminium alloy radiator fin material is characterized by comprising the following materials in parts (100 parts) by weight: 0.5-0.8 part of silicon (Si), 0.6 part or below of ferrite (Fe), 0.1 part or below of copper (Cu), 1.4-1.8 parts of manganese (Mn), 0.03 part or below of magnesium (Mg), 2.3-2.7 parts of zinc (Zn), 0.05-0.2 part of zirconium (Zr) and the balance of aluminium (Al) and other unavoidable impurity microelements.
