Abstract

The invention relates to foils with alloying component proportioning and a method for making the same, in particular to aluminum foils used for the production of a radiator of an air conditioner and a method for making the same, belonging to the aluminum product processing field. The invention aims to overcome the defects existing in the prior art and provide air conditioner foils which are made by elements of iron, manganese, silicon, titanium and aluminum with the optimized component proportioning through processes of cast-rolling, cold-rolling and annealing; the aluminum foils have the advantages of compact structure and excellent comprehensive performance, and particularly facilitate the reduction of thickness and lower manufacturing costs; moreover, the aluminum foils can realize that air conditioner fins are not broken when the fins undergo the high-speed punching, thereby meeting market requirements.

Description

technical field [0001] The invention relates to a foil with an alloy composition ratio and a preparation method thereof, in particular to an aluminum foil suitable for producing air-conditioning radiator fins and a preparation method thereof, belonging to the field of aluminum product processing. Background technique [0002] With the development of modern market economy, the fierce competition in the air conditioner market and the narrowing of profit margins are becoming more and more obvious. Reducing the cost of air conditioner fin aluminum foil and improving the forming efficiency are the focus of air conditioner manufacturers. Therefore, research and development of thin and high-performance air-conditioning foil products is the main trend of air-conditioning foil technology progress. [0003] The development of air-conditioning foil has undergone many changes. The first is the thickness, from the initial 0.2mm to 0.12-0.16mm in the 1980s, 0.10-0.115mm in the 1990s, and ...
