The present invention relates to a roll bond panel used for refrigerator evaporators, solar heat collecting plates, and the like. Roll bond panels include those with bulges on both sides and those with bulges on one side. Conventionally, A1100 sheets are used for double-sided bulging roll bond panels.
What was used was one in which a pressure bonding agent was interposed in a predetermined form to cause pressure bonding, and fluid pressure was introduced into the non-crimped portion to bulge that portion. However, this double-sided bulging roll bond panel had a problem of low strength. In addition, A1100 is available as a single-sided bulging roll bond panel.
The plate and the A3003 plate are crimped together with an anti-crimping agent in a predetermined form, and fluid pressure is introduced into the non-crimped part so that only the A1100 plate side bulges in that part. It was getting worse. However,
There was a problem that A3003 plate had poor corrosion resistance and was not suitable for use in a corrosive environment. The object of the present invention is to provide a roll bond panel that solves the above problems. The roll bond panel according to the invention comprises two
At least one of the metal plates contains 3.5 to 4.5 wt% of zinc and 0.2 to 0.5 wt% of magnesium, with the remainder being aluminum and unavoidable impurities. It consists of a clad metal plate, and a pure aluminum layer is present on at least the outer surface of the other metal plate. In the above, the aluminum alloy containing 3.5 to 4.5 wt% zinc, 0.2 to 0.5 wt% magnesium, and the balance consisting of aluminum and unavoidable impurities has age hardening properties, and its strength increases after aging, such as A3003. becomes larger than Pure aluminum also has excellent corrosion resistance. Therefore, at least one of the two metal plates contains 3.5 to 4.5 wt% zinc and 0.2 to 0.5 wt% magnesium.
%, with the remainder being aluminum and unavoidable impurities, and a clad board in which pure aluminum skin material is clad on the outer surface of the aluminum alloy core material, the strength of the roll bonded panel is increased, and the strength of the skin material side is increased. It has excellent corrosion resistance and can be used with the skin side of the clad plate facing the corrosive atmosphere. Furthermore, if the other metal plate is a pure aluminum plate such as A1100, A1050, or A1230, which does not have age hardening properties and has a strength smaller than that of the above-mentioned clad plate after age hardening, annealing and expansion tubes will be difficult. By performing an aging treatment during this period, it is possible to obtain a single-sided bulged roll bond panel in which only the pure aluminum plate side is bulged.
The reason for limiting the zinc content to 3.5 to 4.5 wt% and the magnesium content to 0.2 to 0.5 wt% in the above is as follows. In other words, if the content of zinc and magnesium is less than the lower limit, the effect of improving strength due to aging cannot be obtained, and if the content of zinc and magnesium exceeds the upper limit,
This is because crimping with other metal plates will not work properly. Further, the cladding ratio of the skin material (the ratio of the thickness of the skin material to the total thickness) is preferably 5 to 20%. If it is less than 5%, sufficient corrosion resistance cannot be obtained,
This is because if it exceeds 20%, sufficient strength cannot be obtained. In order to make the pure aluminum layer exist on at least the outer surface part of the entire other metal plate among the two metal plates, the other metal plate is a pure aluminum plate,
Alternatively, it is preferable to use a clad plate whose outer surface is clad with pure aluminum skin material. A1100, A1050, A1230, etc. are used as pure aluminum. The roll bond panel according to the invention comprises two
At least one of the metal plates contains 3.5 to 4.5 wt% of zinc and 0.2 to 0.5 wt% of magnesium, with the remainder being aluminum and unavoidable impurities. Since it is made of clad plates, it has greater strength than the conventional two metal plates made of A1100 material. Moreover, if a metal plate having a strength lower than that of the above-mentioned Kudo plate after age hardening is used as the other metal plate, a one-side bulge can be obtained. Further, since the outer surface of the clad plate is covered with pure aluminum having excellent corrosion resistance, the clad plate can be used in a corrosive environment with the clad plate facing the corrosive atmosphere. Furthermore, since the pure aluminum layer is present on at least the outer surface of the entire other metal plate, corrosion resistance is excellent. This invention will be explained below with reference to the drawings. In Figure 1, roll bond panel 1
The A1100 skin material 3 is clad with a cladding ratio of 15% on the outer surface of an aluminum alloy core material 2 containing 3.6 wt% zinc and 0.24 wt% magnesium, with the remainder being aluminum and unavoidable impurities.
A first metal plate 4 made of a clad plate of mm, and A1100
It consists of a second metal plate 5 made of a plate, and bulges 6 that bulge only toward the second metal plate 5 at predetermined non-crimped portions. This single-sided bulging roll bond panel 1 is manufactured by the following method. That is, an anti-crimping agent is printed in a predetermined form on the core material 2 of the first metal plate 4,
A second metal plate 5 is placed on top of it and hot rolled,
Subsequently, cold rolling is performed to obtain a three-layer laminated board with a final board thickness of 1.2 mm. Next, this three-layer laminated board was heated to
After annealing at 400℃ for 20 minutes, the first
The core material 2 of the metal plate 4 is aged and hardened. Thereafter, this is placed in a mold, and fluid pressure is introduced into the non-crimped portion to bulge only the second metal plate 5 side. In this way, a single-sided bulging roll bond panel 1 with a bulging portion 6 on one side is manufactured. Evaluation Test In order to evaluate the performance of the roll bond panel 1, the tensile strength, yield strength, and elongation of the clad plate (first metal plate 4) were measured. Also, for comparison, the tensile strength of a plate made of A1100-O material,
Yield strength and elongation were measured. These results are shown in the table below.

造される。[Table] Furthermore, as a result of investigating the corrosion resistance of the skin material 3 side of the cladding board that comes to the outside when it becomes roll bond panel 1, and the corrosion resistance of the board made of A1100-O material, it was found that both were equivalent. It was excellent. Another embodiment of the invention is shown in FIG. In Figure 2, roll bond panel 1
1 contains A1100 on the outer surface of an aluminum alloy core material 12 containing 3.6 wt% zinc and 0.24 wt% magnesium, with the balance being aluminum and unavoidable impurities.
Two 2.0 mm thick clad plates 14 made by cladding leather material 13 at a cladding rate of 20%, and bulging portions 1 bulging out on both sides at predetermined non-crimped portions.
5 and more. This double-sided bulging roll bond panel 11 is manufactured by the following method. That is, an anti-crimping agent is printed in a predetermined form on the core material 12 of one clad plate 14, the other clad plate 14 is stacked on top of that with the core material 12 facing down, and hot rolling is performed. Cold rolling is performed to obtain a four-layer laminated board with a final thickness of 1.0 mm. Next, this 4-layer laminated board was heated at a temperature of 400℃ for 20 minutes.
After being annealed for 40 minutes, the core material 12 is aged and hardened by leaving it for 40 minutes. Thereafter, this is placed in a mold, and fluid pressure is introduced into the non-crimped portion, causing the non-crimped portion to bulge out on both sides. In this way, a double-sided bulge roll bond panel 11 with bulges 15 on both sides is manufactured.
