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~
One or more of 2.5% or B0.5-2.0%, and
An alloy consisting of 1.0-3.0% Mg as an essential component, other unavoidable impurities, and a residual Al, or at least one or more of V0.5-2.5%, Cr0.5-2.5%, or B0.5-2.0% , and Mg1.0-3.0%, and
A wrought alloy consisting of 0.02 to 0.3% Cu as an essential component, other unavoidable impurities, and residual Al can be made into a beautiful straight-grained material by etching alone, or by chemical polishing or electrolytic polishing after etching. We discovered that a striped pattern can be formed, and we applied treatments such as anodizing, electrolytic coloring, dyeing, and painting to such pattern-forming materials as needed (applications).
They created something that was fit for purpose.

る。 Here, the reason for containing 1.0 to 3.0% Mg is Mg
If the amount is less than 1%, the elements V, Cr, or B, which are used to create patterns, will segregate significantly in the ingot, and as a result, unless the amount of surface cutting of the ingot is increased, it will not be possible to achieve the desired beautiful appearance. The pattern cannot be obtained, and for this reason, it is necessary to add a large amount of V, Cr, or B. If a large amount of V, Cr, or B is added in this way, the ingot will be damaged during casting. This is because cracking becomes more likely to occur, making stable casting difficult.On the other hand, if the Mg content is too high, exceeding 3%, it not only reduces productivity during processes such as casting and rolling. This is because the above-mentioned anti-segregation effect is also reduced and the benefits are poor. Also, Mg
Addition not only has such a large effect, but also has secondary effects such as improving strength.
In other words, by containing 1.0 to 3.0% Mg, Mg
If it does not contain 5052 alloy, the tensile strength is only about the same as that of 1200 alloy, but it becomes stronger than 5052 alloy.

しく悪いものともなる。 In addition, V is used as a component of aluminum alloy.
0.5-0.2%, 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. In addition, when a wrought aluminum alloy material containing too much V, Cr, or B is etched,
The beautiful straight-grain pattern does not appear, that is, V is 2.5% or less, Cr is 2.5% or less,
B could not produce beautiful patterns unless it was an aluminum alloy with a content of 2.0% or less. Furthermore, the etched aluminum alloy wrought materials containing V, Cr, or B in excess of the upper limit of addition,
Etching makes it extremely difficult to remove the smut that has adhered to the surface, and it also has a significant negative effect on the properties of the surface film formed in subsequent treatments. 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.
又、さらにCuを添加したのは、Cuを含ませて

る。尚、このCuの含有量を0.02〜0.3％としたの
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.
そして、上記のような組成のアルミニウム合金

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.
尚、エツチング処理に際して、0.15〜0.80g／
ｄm2、より望ましくは0.25〜0.70g／ｄm2の溶解

ぎる場合には荒れた筋模様となつて、美麗な表面
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.
又、エツチング処理が、上述のように弱すぎる

筋模様であつて、しかも光輝性に富んだものとな
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.
尚、このような美麗な柾目調のような筋模様の

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.
