Conventionally, methods for forming patterns on the surface of aluminum alloys include mechanical means such as embossing or chemical means such as etching.
However, these means, for example the former means, use rolling pressure rolls or press molds, and can only be applied to flat plates, and since rolls and molds are used, the equipment itself is correspondingly large. In addition, the latter method requires special techniques and equipment, and requires special techniques and equipment, as it involves etching the photoengraved original image, masking it with paint, etching, and printing. However, the productivity is low, and furthermore, it inherently has the disadvantage that it can only be applied to small items.

The inventor has determined that at least V0.5~2.5%, Cr0.5~
2.5%, one or more of B0.5~2.0%,
Aluminum alloy consisting of Mg0.5-1.5%, Mn0.5-1.0%, and residual Al including other unavoidable impurities, or at least V0.5-2.5%, Cr0.5-2.5
%, one or more of B0.5 to 2.0%, and Mg0.5
~1.5%, Mn0.5~1.0%, Cu0.02~0.3%,
A wrought aluminum alloy material containing residual Al and other unavoidable impurities can be subjected to etching treatment alone, or after etching treatment, to chemical polishing or electrolytic polishing treatment to form, for example, a beautiful straight-grained striped pattern. This pattern-forming material was then subjected to treatments such as anodizing, electrolytic coloring, dyeing, and painting, depending on the need (application), to create materials suitable for the purpose.

ば強度向上にもなる。 Here, the inclusion of 0.5 to 1.5% Mg and 0.5 to 1.0% Mn means that Mg is less than 0.5% and Mn is 0.5%.
If the total amount of Mg and Mn is less than 1%, the elements V, Cr, or B, which are used to create patterns, will segregate to a large extent in the ingot, and as a result, the amount of surface removal of the ingot will decrease. Unless it is made larger, it will not be possible to obtain the desired beautiful pattern, and for this reason, it will be necessary to add a large amount of V, Cr or B.
When a large amount of V, Cr or B is added in this way,
This is because the ingot tends to crack during casting, making stable casting difficult;
If Mg exceeds 1.5%, Mn exceeds 1.0%, and the total amount of Mg and Mn is too large, productivity will decrease during processing such as casting and rolling.
For example, if there is too much Mn, giant crystals of Mn-based compounds will be formed, resulting in uneven patterns and a loss of beauty.Furthermore, if alumite treatment is performed after pattern formation, Mn This is because it naturally develops color, which has disadvantages such as being sensitive to heat history and causing color unevenness, and also has little effect on preventing the segregation of V, Cr, or B. Also, Mg
As a side effect, the addition of Mn also improves strength, for example.

る。 In addition, V is used as a component of aluminum alloy.
0.5-2.5%, Cr 0.5-2.5%, or B 0.5-2.0%
The reason for using aluminum alloys is that unless the aluminum alloy contains at least V, Cr, or B, a straight-grained streak pattern cannot be produced simply by etching. This is because if the number of grains is small, clear straight-grained streaks cannot be produced by etching alone. That is, by including 0.5% or more of V, Cr, or B, a beautiful straight-grained pattern appeared when the wrought aluminum alloy material was etched.
又、Ｖ，Cr又はＢを多量に加えすぎたアルミ

く悪いものともなる。 Furthermore, if a wrought aluminum alloy material containing too much V, Cr, or B is etched, the beautiful straight-grained pattern will not appear. In other words, V will be less than 2.5% and Cr will be 2.5%. Below, B
A beautiful pattern could only be created with an aluminum alloy containing less than 2.0% aluminum. Furthermore, in the case of etched aluminum alloy wrought materials containing V, Cr, or B in excess of the upper limit added, it becomes extremely difficult to remove the smut that has adhered to the surface during etching, and subsequent processing is difficult. It also has a large adverse effect on the properties of the surface film formed. In addition, the workability of aluminum alloy wrought materials containing V, Cr, or B exceeding the above-mentioned upper limit values becomes significantly poor, especially the workability in the direction perpendicular to the direction of the streaks that appear during etching treatment. It can also be extremely bad.

は、少なすぎる場合には上述の効果に乏しいから
であり、又、多すぎる場合には鋳造に際して鋳塊
が割れやすくなるからである。 Further, the reason why Cu was added was that the inclusion of Cu improved the glitter, and as a result, the straight-grain tone and streaked pattern became even clearer, which had a remarkable effect on the appearance of the pattern. Also, depending on the application, for example, if plating processing such as electroless plating is required, special pre-treatment (activation treatment) is required since general alloys containing Mg have poor adhesion. This is because, if Cu was included, a sufficiently good plating film could be obtained in a normal plating process without such special pretreatment. The reason why this Cu content is set to 0.02 to 0.3% is because if it is too small, the above-mentioned effects will be poor, and if it is too large, the ingot will easily break during casting.

図に示す如くの美麗な筋模様が現出する。 Then, by etching the wrought aluminum alloy material having the above composition at a melting rate of 0.15 to 0.80 g/dm 2 , more preferably 0.25 to 0.70 g/dm 2 , a clear straight grain pattern can be obtained. A striped pattern can be easily formed. For example, by alkaline etching with aqueous caustic soda solution, the first
A beautiful striped pattern appears as shown in the figure.

になりにくいからである。 In addition, during the etching process, 0.15 to 0.80g/
The reason for etching with a dissolution amount of dm 2 , more preferably 0.25 to 0.70 g/dm 2 is because if the etching is too weak, it will be difficult to obtain a clear and beautiful striped pattern. This is because if the surface is too strong, a rough streak pattern will appear, making it difficult to obtain a beautiful surface.

る。 Also, if the etching process is too weak as mentioned above, there is a problem, but if the etching process is only relatively weak, electrolytic polishing or chemical polishing can be applied after the etching process. This not only eliminates the above-mentioned drawbacks, but also makes it excellent for applications that require brightness, such as decorative products. Furthermore, for applications that require such brightness, it is sufficient that the etching treatment is slightly weaker than the above-mentioned etching treatment alone; It is not limited only to the degree. In other words, the amount of material dissolved is 0.10~
0.60g/ dm2 , more preferably 0.20-0.50g/ dm2
After performing the etching treatment described above, electrolytic polishing or chemical polishing under normal conditions results in a beautiful and clear striped pattern with high brightness.

えられる。 The mechanism by which such a beautiful straight-grained streak pattern appears is thought to be as follows. In other words, the aluminum alloy used in the present invention contains additive elements such as V, Cr, and B in amounts exceeding the solid solubility limit at the stretching temperature, so that the aluminum alloy has a thickness of approximately 20 μm.
There are crystallized substances of a size larger than 100%, which are crushed along the stretching direction during the stretching process and become streak-like, and as the crystallized substances fall off and dissolve during the etching process, It is thought that the aluminum surrounding the crystallized material also melts, creating irregularities perpendicular to the processing direction, resulting in a surface with a striped appearance.
