Fin material for aluminum alloy heat radiator

Abstract

The invention provides a fin material for an aluminum alloy heat radiator, which can effectively solve the problems that the conventional fin material for the aluminum alloy heat radiator, which is machined by using the traditional 3003 aluminum alloy, has the defects of low strength and poor collapse resistance. Meanwhile, with the adoption of the fin material for the aluminum alloy heat radiator provided by the invention, the material thickness can be greatly reduced; and the raw material cost is reduced; and a heat radiator pipe can be prevented from being corroded, so that the service life of the entire heat radiator can be prolonged. The fin material for the aluminum alloy heat radiator is characterized by comprising the following materials according to the total parts by weight of 100: 0.5-0.8 parts of silicon (Si), less than or equal to 0.6 parts of ferrum (Fe), less than or equal to 0.1 parts of copper (Cu), 1.4-1.8 parts of manganese (Mn), less than or equal to 0.03 parts of magnesium (Mg), 2.3-2.7 parts of zinc (Zn), 0.05-0.2 parts of zirconium (Zr), and the balance of aluminum (Al) and other unavoidable impurity trace elements.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy materials, in particular to an aluminum alloy radiator fin material. Background technique [0002] Existing aluminum alloy radiator fins are mostly processed by traditional 3003 aluminum alloys. The traditional 3003 aluminum alloy materials include the following materials with a total weight of 100 parts: silicon (Si) ≤ 0.6 parts, iron (Fe) ≤ 0.7 parts, copper (Cu) 0.05 ~ 0.2 parts, manganese (Mn) 1 ~ 1.5 parts, zinc (Zn) ≤ 0.1 parts, the rest is Al and other impurity trace elements, of which other impurity trace elements do not exceed 0.15 parts, Due to the low strength of the traditional 3003 aluminum alloy material, especially under high-temperature brazing conditions, the plate heat exchanger fins processed by the traditional 3003 aluminum alloy material have poor collapse resistance; and the aluminum alloy processed by the traditional 3003 aluminum alloy The thickness of radiator fins...
