Embodiment Construction

[0020] In the research and development of "full-adaptive air-conditioning foil", the general technical idea is to adjust the synergistic alloying elements and their content in the aluminum matrix to obtain a balance in the mechanical properties or changes in mechanical properties of the air-conditioning foil Effect, so it is suitable for stamping processing of various punching machines.

[0021] In alloyed aluminum foil, the analysis of the role of each alloying element is as follows:

[0022] Fe within a certain range can promote grain refinement, improve structure uniformity and increase strength; Si can improve plasticity and Fe together can effectively reduce the second phase size and grain size in the casting and rolling process; Cu and Mn form a solid solution However, the addition of Cu makes the substrate easy to crack. Although the addition of Mn can refine the grains and strengthen the alloy, it is easy to make the grain size difficult to control in different content...

Abstract

The invention discloses a universal aluminium alloy air-conditioner foil and a manufacturing method thereof. The universal type means to the punching processing technology suitable for various punches. The universal aluminium alloy air-conditioner foil is characterized in that as for the alloying elements distributed in Al base, the weight ratio of Fe to Si is controlled to be 4-6:1, so that the aluminium alloy air-conditioner foil tends to Fe causing 45-degree earing and tends to Si causing 0 or 90-degree earing combined action in the punching process so as to improve the evenness of earing direction.

Description

technical field [0001] The invention relates to aluminum foil material technology, in particular to a general-purpose aluminum alloy air-conditioning foil and a manufacturing method thereof. The universal type refers to the stamping process that can be applied to a variety of punching machines. The air-conditioning foil can meet the performance requirements of various professional punching machines used by air conditioner manufacturers for stamping materials, and avoid the need for professional punching machines from different suppliers. Conditions corresponding to different air-conditioning foil materials are required, and the technical effect of unifying the air-conditioning foil materials is achieved. Background technique [0002] Air-conditioning foil is an aluminum alloy material, in which alloying elements are often chosen to use Fe, Si, Mn, Ti, Cu, etc., for example, the actual production includes "Fe+Si+Ti", "Fe+Si+Cu+Ti ", "Fe+Si+Mn+Ti" and other combinations. In ...
