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 relates to a full applicability air conditioning foil and manufacturing method thereof. Al base only comprises Fe, Si and Ti three alloying elements, and the weight ratio of the three alloying elements is controlled to be that Fe: Si: Ti is equal to 60-80: 15-16: 1; the weight ratio causes aluminium alloy air conditioning foil is subject to combined action of Fe leading to 45 degrees of earing and Si leading to 0 or 90 degrees of earing in stamping process, so as to improve uniformity in earing direction, Ti therein realizes grain refining function, so that the grain size of air conditioning foil is less than or equal to one class, and plasticity of air conditioning foil is improved. The air conditioning foil can meet the performance requirement of various special punches used by the current air conditioner factories to stamping material, avoids the condition restriction that different special punch requirements of different suppliers are corresponding to different air conditioning foil materials and achieves the technical effect of unionization of air conditioning foil material.

Description

technical field [0001] The invention relates to the technology of aluminum foil materials, in particular to an all-purpose air-conditioning foil and a manufacturing method thereof. The full applicability 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, avoiding the professionalism of different suppliers. The punching machine needs conditions corresponding to different air-conditioning foil materials, which achieves the technical effect of unifying the air-conditioning foil materials. 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 order to adapt to th...
