Aluminum alloy material used for processing air-cooling fin in power station

Abstract

The invention provides an aluminum alloy material used for processing an air-cooling fin in a power station. According to the aluminum alloy material, the problem in the prior art that the air-cooling fin in the power station, which is processed from conventional 3003 aluminum alloy, is low in strength can be solved, the anti-collapse performance of fin material under high-temperature brazing condition is improved effectively, and the service life of the fin material is prolonged, and furthermore, due to the adoption of the aluminum alloy material used for processing the air-cooling fin in the power station provided by the invention, the thickness of the fin material is reduced effectively, and the production cost is lowered. The aluminum alloy material is characterized by comprising the following materials being 100 parts in total weight: Si being smaller than or equal to 0.3 part, Fe being smaller than or equal to 0.5 part, 0.5 -0.7 part of Cu, 0.65-1 part of MN, 0.08 -0.1 parts of Ti and the balance of Al and other inevitable impurity elements.

Description

technical field [0001] The invention relates to the technical field of processing aluminum alloy materials, in particular to an aluminum alloy material used for processing air-cooled fins of power stations. Background technique [0002] The existing air-cooled fins of power stations are mostly processed by traditional 3003 aluminum alloy materials. 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, 0.05-0.2 parts of copper (Cu), 1-1.5 parts of manganese (Mn), zinc (Zn) ≤ 0.1 parts, the rest are Al and other impurity trace elements, of which other impurity trace elements do not exceed 0.15 The disadvantage is that the power station air-cooled fins processed by traditional 3003 aluminum alloy materials have low strength, and the anti-collapse performance of the material is also low under high-temperature brazing conditions, so the service life of the product is short; ...
