For DI moldability users, when it is lower than the lower limit 値, the effect is small and resistance to bulging If it is not enough and exceeds the upper limit 値, coarse compounds will be formed, which will reduce moldability and weldability. C u: 0 · 1 0 to 0.7 0 wt%, M g: 0 · 2 0 to] · 2 0 wt%, these elements will give strength to the aluminum alloy plate, and at the same time work harden to a large size, which can increase the expansion resistance.

In addition, a high earing rate of 45 ° when a cylindrical container is drawn (extended) at a low rolling rate can be imparted. However, when it is lower than the lower limit 値, it has less effect, and when it exceeds the upper limit 耳, the ear will change, and the yield of the finished product will be reduced, and coarse compounds will be generated to reduce moldability. Ideally, Zr in 〇. 1 3 ~ 0. 9 wt%. In addition to the foregoing composition, when Cr is 0.35 wt% or less, the recrystallized particles can be miniaturized and the outer panel of the container can be more beautiful. Moreover, Cr It will inevitably be mixed from the regrind, and it contains less than 0.001 wt% in the usual melt manufacturing. Therefore, in order to make the effect of adding Cr more significant, it is necessary to make it contain more than 0 · 0 1 wt. %. Ideally, C r contains 0.1% by weight or more, and more preferably 0.15 wt% or more. However, when it exceeds the upper limit 値, coarse compounds are formed and the moldability is reduced. 0 Impurities (impurities) that cannot be avoided Elements that are difficult to manage are mixed in from the raw metal, regrind, etc., but the content of these is, for example, 0.2 5 w ％% or less of Z η, 0.0 5 wt% or less of G a and V, each of which is 0.05. Other elements below wt%, however within this range even Containing other elements for management will not hinder the effect of the present invention. Next, the ear rolling rate of 45 ° for the light rolling direction is 4 to 7%. When the cylindrical blank of the aluminum rolled sheet is deeply drawn to form In the case of a cylindrical container, if it is a soft material, it will form a convex shape that develops into a mountain shape at the periphery of the container at 0 ° and 90 ° with respect to the rolling direction, and it will be at 4 5 ° C when the material is strong processed. The perimeter part of the container is formed into a mountain-shaped -9-(6) (6) 200411970 The protrusion is called an ear, but in order to become a finished product (productization), it is necessary to eliminate it, so that It becomes an important factor to reduce the yield of the finished product of the material. Therefore, it is usually required that the ears are not biased to 0, 90, or 4 5. The board with uniform ears generated in the direction is used. However, 'DI molding section is required When it is a rectangular container, as described above, the use of an oval blank material that is more rectangular than the rectangular one will be a good yield during the cutting stage of the board. Work or short diameter ' When it is parallel to the direction of the milk, it can be stretched (drawn) and the perimeter of the container will develop in the direction of 0 °, 90 °. The valley will be formed in the 4 5 direction, which will reduce the finished product. For this reason, if a plate with long ears is used if it is used in the direction of 4 5 in advance, it can be formed into a uniform ear by DI processing, so that the yield of the finished product can be improved. That is, the above-mentioned conventional type As the battery container for portable use, the ear material with an ear rate of 4 Q / 4 is used, and a D i finished product with a high finished product yield can be obtained. [Embodiment] Next, the description of the present Invented method for manufacturing aluminum alloy plate. The semi-continuous casting method is used to make the ingot of the aluminum alloy with the aforementioned composition into an ingot, and to perform homogenizing treatment and hot rolling, and to obtain the predetermined strength through intermediate annealing and final (finished) rolling. And has 4 5. Ear-rate aluminum alloy plate. -10- (7) (7) 200411970 The homogenization treatment of ingots obtained as a result of the semi-continuous casting method is used to maintain the high temperature for easy roll rolling to remove casting segregation. The temperature Ideally, it is kept at 500 ~ 600c for more than one hour. If the heating temperature is too low or the holding time is too short, the size of the crystallized material becomes small ', which causes the annealed recrystallized particles to become coarse, so that the appearance of the outer panel cannot be finished to be beautiful after D1 molding. When the final rolling rate is low, it is easy to make the ear rate exceed 7%, so that the predetermined strength cannot be obtained. When the heating temperature is too high, there is a possibility of local melting. A more desirable homogenization temperature is in a range of 5 2 0 ° C or higher and 5 9 0 t or lower. Intermediate annealing is to make the recrystallized structure finer, so it is ideal to perform continuous annealing with a temperature increase rate of 5 t / sec or more, and its heating temperature is 400 ° C or more. It can also be used at higher temperatures. Melt. The holding time is ideally less than 0 seconds. The final rolling will complement the homogenization treatment temperature for 40. The effect of ear rate will become greater. Therefore, if the homogenization treatment is maintained at 500 ° C to 600 ° C for more than an hour, and the final rolling is performed at a rolling rate of 25 to 55%, a 45 ° ear rate can be obtained. % Of aluminum alloy plate. If the rolling rate of the final rolling does not reach the lower limit 値, the predetermined strength cannot be obtained and the 4 5 ^ ear rate will become low ', but when the upper limit 値 is exceeded, the 45 ° ear rate will become too high, so that When the rectangular cross-sectional container is D1 molded, the yield of the finished product is reduced, and the ductility is reduced. Therefore, when D1 is molded, cracks are easily generated at the shoulder of the mold. And the board obtained as above will be formed into rectangular cross-section containers of various sizes as described above, for example, with a plate thickness of 0.6mm 'and implemented -11-(8) (8) 200411970 extension processing and ironing Processed into containers. After assembling the battery component, the container is aligned with the cover, and pulsed laser welding is performed to align the cover to form the battery. However, before assembling the battery component to the aforementioned container, the container is set at 40 to 70 °. When heat-treated at a temperature of C, it will age harden and become high-strength, and it can be used in a stable state. Next, pulse laser welding for fixing the lid to the container will be described. Align the cover with the container, and place the alignment cover in the atmosphere, or use an inert gas such as argon (blunt gas) as an auxiliary gas (adjuvant) to weld as needed. Although the welding conditions depend on the thickness of the board, the welding time can be appropriately set by setting the pulse time, output, distance from the focus, and welding speed. In other words, although the pulse time is 0.3 to 5 ms, 1.5 to 15 joules / point, the distance from the focal point is -5 to + 10 mm, and the range of the welding speed is 1 to 30 mm / sec. Appropriately adopted, but these conditions are not limited by the above. Next, specific examples will be described. (Example) An aluminum alloy molten metal is produced by pre-melting, and is cast by a semi-continuous casting method with cooling water from a mold of 2.5 to 3.0 liters / cm minutes and an ingot pull-out speed of 40 to 60 mm / minutes. An ingot with a thickness of 530 mm and a width of 1100 mm. On the other hand, the Zr. System was added using AhZi master alloy, the Ti system was added using AhTi master alloy, and the B system was added using A 1-T i-B master alloy. The composition is shown in Table 1. -12- (9) (9) 200411970 After the ingot is cut, it is subjected to a homogenization treatment, and hot rolling is started after being held 'to obtain a hot-rolled sheet having a thickness of 6 mm at a completion temperature of 400 ° C. Next, cold rolling was performed four times to obtain cold-rolled sheets of various thicknesses, and intermediate annealing was performed. The intermediate annealing treatment is heated to 5 20 ° C ′ by electromagnetic induction heating, and then held for a few seconds, and then water quenched. After the water quenching, cold rolling was performed to form a rolled sheet having a thickness of 0.6 mm. The following measurement was performed using the rolled sheet. The measurement results are shown in Table 2. < 45 ° ear rate > The round billet was deep-extended into a cylindrical container, and the 45 ° ear rate was measured. Ear rate (%) < 〇〇 (Η1-Ή2) /0.5 (H1 + H2) Here, Η 1: the average of the distance from the bottom to the mountain 値 Η 2: the distance from the bottom to the valley Average yield of finished products> After the oval blank is drawn (extended) and formed, it is subjected to ironing processing, and a bottomed container having an inner size of 5 mm in length X 25 mm in width x 50 mm in depth is manufactured In order to make the edge of the container flat, cutting is performed, and the yield of the finished product is measured. The ironing rate is 50%. The yield of the finished product is calculated by the following formula.

Even if the welding speed of the pulse laser is fast, no welding cracks can be seen, which is indeed superior to welding. The samples (Sample Nos. 3, 7, and 9) within the scope of the present invention that also contained Cr show that the finished product of the container is extremely excellent. On the other hand, as comparative examples Z r, T i, and B All of them are in the impurity range, and the sample with a low ear rate of 45 ° (sample number i 3) has a low yield of the finished product and weld cracks. It can be seen that its weldability is low. In addition, Zr, Ti or B is a sample (sample No. 14 to 22) where two or two elements coexist, resulting in welding cracks, and it can be seen that the weldability is low. In addition, in the samples (Sample Nos. 20 to 22) in which the content of Zr, Ti, or B exceeded the range of the present invention, cracks occurred during D 1 molding, and it was found that the moldability was poor. As stated above, the aluminum alloy plate of the present invention has a high ear rate at 45 ° and excellent pulse laser weldability, so that a battery container with a rectangular cross section can be manufactured with a high yield, and the container can be processed at a high speed. Since the lid is welded, it has high productivity when manufacturing the battery, and has various industrial effects. [Brief description of the drawing] Fig. 1 is a perspective view (stereoscopic view) 3 of a battery container with a lid and a rectangular cross section where pulse laser welding is performed. Fig. 2 is a plan view of a slightly oval blank when a container is to be subjected to extension processing. -17- (14) (14) 200411970 [Explanation of symbols] 1: (battery) container 2: lid (sub) 3: welding line for pulse welding of container 1 and lid 2 4: blank 5: DI processing , The dashed line of the position where the punch will touch.
