。[Detailed Description of the Invention] [Industrial Application Field] The present invention is suitable for producing containers and their caps, etc., and is characterized by deep drawing processability, especially small cup edges, and by sulfuric acid anodizing treatment, which produces a milky white color or an aged appearance. The present invention relates to a method for producing an aluminum alloy plate having both the properties of

た。[Prior Art] Conventionally, materials with good deep drawing properties have been used for pots, lunch boxes, and other utensils, and the deep drawn materials have been colored with paint or electrolytic coloring. However, since various colors can be obtained by natural coloring by anodizing, materials that develop a milky white color have recently become preferred as materials for utensils.

処理で乳白色がＮｊられるアルミニウム合金板が装甲さ
れるようになった。However, when this milky-white material is deep-drawn for use in making utensils, large wavy cup lugs are produced at the opening, which have to be trimmed, resulting in a low yield. Furthermore, if the cup selvage is large, the variation in the plate thickness after drawing is large, and wrinkles are likely to occur on the material surface, which impairs the appearance. For this reason, aluminum alloy plates, which do not have cup ears and whose milky white color is changed to Nj by anodizing treatment, are now being armored.

As a way to improve both at the same time, method (■) is effective in preventing skin roughness, especially in the case of "squeezing", and can obtain a uniform anodic oxide film, but it is not effective in reducing the cup ears mentioned here. It seems so. In addition, (2) proposes a heat treatment method to obtain a uniform anodic oxidation film, but it is intended to make the film milky white and cannot reduce cup edges during deep drawing. ■ is for obtaining a milky white color and cannot reduce cup ears. (2) is an alloy that provides strength and workability, but because of the high amount of Si, a milky white color cannot be obtained. ■ is the one that reduces the cup selvage during deep drawing, but this is because the Si content is 0.35νt% or more.
It is difficult to obtain a stable milky white color.
そこで、本発明は深絞り時のカップ耳の発生が小さく、

るものである。Therefore, the present invention reduces the occurrence of cup ears during deep drawing.
The present invention provides a method for stably and inexpensively manufacturing an aluminum alloy plate that develops a milky white color when anodized.

要がある。In the above composition, Fe is an element necessary to obtain a milky white anodic oxide film. If the amount is less than 0.3vt%, a milky white color cannot be obtained, and if it is added in excess of 2.2V%, the Al-Fe compound will be unevenly dispersed.
Since it exhibits a streaky pattern, impairs the appearance, and also deteriorates moldability, it is necessary to keep the content between 0.3 vt% and 2.2 vt%.

。Si has the effect of reducing the 45° angle during deep drawing of Al-Fe alloys, but if too much Si is added, it tends to precipitate in the form of simple Si, turning the anodic oxide film black and giving it a milky white color. adversely affect. If the amount is less than 0.05wt%, the effect of making the ears smaller cannot be obtained, and 0.3wL%
If it exceeds the above, it is difficult to obtain a milky white anodic oxide film.
It must be between 0.05vL% and 0.3vL%.

下にする必要がある。Similar to Si, Cu has the effect of reducing the selvedge in the 45@ direction of the Al-Fe alloy. If the amount of melon is less than 0.05vL%, the effect cannot be obtained, and if it exceeds 0.5wt%, the effect of reducing the ear rate cannot be further obtained and the moldability is significantly reduced, so 0.05vt% or more It is necessary to make it 0.5vt% or less.

えない。In addition, Ti up to 0.1 wt%, 0.05%, is often added to modify the crystal structure during alloy melting.
The addition of B up to the above does not particularly affect the color tone and cup edge of the anodic oxide film produced by the method for producing the alloy of the present invention, so there is no problem.

。In the manufacturing conditions, soaking is performed at a temperature of 560°C or higher in order to obtain the effect of reducing the selvage rate by adding St and Cu to the Al-Fe alloy, and
Al-F is a metastable phase such as Al m Fe.
This is to phase change the e compound to Al3Fe, which is a stable phase, and obtain a good milky white anodic oxide film. and,
Holding for 5 hours or more is required to obtain these effects.
