Problems solved by technology

[0002] The quality of aluminum foil for household air conditioners, refrigerators and automobile air conditioners depends on the ratio of raw materials and the refining process. The patent number is 02138192.5, and the patent name is "a kind of aluminum foil and its production method". The aluminum foil produced by this patent method is used in actual use. There are still punching and cracking phenomena, and there is a phenomenon of rewinding in the bending process, and the punching speed is slow. The reason is that the composition of the raw materials and the process cannot completely change the internal structure of the aluminum foil, resulting in poor formability.

Abstract

The present invention discloses one kind of aluminum foil for air conditioner and refrigerator. The aluminum foil is produced with the materials including Al 99-99.50 weight portions, Fe 0.15-0.28 weight portion, Si 0.08-0.18 weight portion, Mn 0.20-0.25 weight portion, Mg <0.05 weight portion, Zn <0.1 weight portion, Cu <0.1 weight portion, Ti <0.08 weight portion, Ni <0.05 weight portion, and Cr <0.05 weight portion, and through smelting, casting and rolling, cold rolling, annealing and other steps. The aluminum foil has homogeneous structure, high elongation and cupping value, moderate strength, and excellent machining and forming performance, and is especially suitable for punching in a high speed punch.

Description

Technical field [0001] The invention relates to aluminum foil for refrigeration equipment such as household air conditioners, refrigerators, and automobile air conditioners. Background technique [0002] The quality of aluminum foil for household air conditioners, refrigerators, and automobile air conditioners depends on the ratio of raw materials and the refining process. The patent number is 02138192.5, and the patent name is "An aluminum foil and its production method". The aluminum foil produced by this patented method is actually used There are still punching and cracking phenomenon, rewinding phenomenon in the bending process, and the punching speed is slow. The reason is that the composition and process of the raw material can not completely change the internal structure of the aluminum foil, resulting in poor processing and formability. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides an aluminum foi...
