０８２合金材。(Prior art) Easy-open cans, which are widely used as beverage cans, consist of a can body (can body) and a can end (can lid).The can body is processed into a cup shape by DI molding.
The can end is scored and riveted (multi-stage stretch molding) to attach tabs, and then it is seamed and joined to the cam body. As a canvas material, JIS300 has excellent deep drawability and ironing workability (DI formability).
4 alloy material or tin-free steel is used, and the can end material is JIS 5052 alloy material with excellent rivet formability for coffee, fruit juice, etc., and JIS 5052 alloy material with higher strength is used for carbonated drinks and beer that generate internal pressure. 5

ればなるほど困難になるため、上記従来材では０．２５
ｍ１程度までの薄肉化が限度であった。(Problems to be solved by the invention) However, when the conventional alloy material mentioned above becomes thinner,
There was a drawback that rivet formability was insufficient and rivet forming cracks were likely to occur. In other words, rivet forming usually involves three stages of stretch forming to form a final rivet with a diameter of about 3 mm, and then attaching tabs (riveting), but this stretch forming becomes more difficult as the board becomes thinner. Therefore, the above conventional material has a value of 0.25
The limit was to reduce the thickness to about ml.
したがって、本発明はリベット成形性に優れ、厚さ０．

ルミニウム合金材を提供することを目的とする。Therefore, the present invention has excellent rivet formability and has a thickness of 0.
The purpose of the present invention is to provide an aluminum alloy material for can ends that can be made thin up to about 20 m+s.

Furthermore, it has been discovered that a more preferable alloy material can be obtained by adding a metal element that improves mechanical strength to this aluminum alloy. The present invention has been made based on this knowledge.

Aluminum alloy material for can end, and (2)

化する。The content of Mg is 2 to 6%. Mg is an important element that provides strength to aluminum alloy materials. If the Mg content is less than 2%, strength improvement is insufficient, and if the Mg content exceeds 6%, rollability and formability deteriorate.
希土類元素の含有量は０．００５〜１％とする。希土類

有量範囲は、コスト面も考慮した場合、０．０５〜０．
５％程度である。Ce, Pr, Nd, Sm and mixtures thereof can be suitably used. Rare earth elements have the effect of improving rivet formability. In other words, adding even a very small amount of rare earth elements can reduce the amount of work hardening of the rivet part during stretch forming, and also make the plate thickness distribution uniform.
Tab attachment through work hardening or local thickness reduction (necking) prevents cracking over time. If the total content of rare earth elements is less than 0.005%, the effect will be small;
If the content exceeds this amount, a coarse intermetallic compound will be formed and the rivet formability will deteriorate. The preferable content range of rare earth elements is 0.05 to 0.05, considering cost.
It is about 5%.

Ｍｎの含有量は０．ＯＳ〜０．５％とする。The content of Mn is 0. OS ~ 0.5%.
Ｍｎは強度を付与し、集合組織（耳）の安定化に寄与す

る条件ては、これら効果が飽和してしまい。エネルギー
コストの増大を招くだけである。First, a molten aluminum alloy containing the above-mentioned components is cast according to a conventional method. Semi-continuous casting is generally used as this casting method, but continuous thin plate casting may also be used to save energy and improve mechanical properties.The obtained ingot is subjected to soaking treatment (homogenization treatment). This soaking treatment condition is as follows:
In order to refine the crystal grains during intermediate annealing, it is preferable to set the soaking temperature to 450 to 600°C and the soaking time to within 48 hours.If the soaking temperature is less than 450°C, the crystal grains of intermediate annealing will be fine. It is difficult to miniaturize the surface, and it is difficult to uniformly and finely roughen the surface electrochemically. Furthermore, if the soaking temperature exceeds 600°C or the soaking time exceeds 48 hours, these effects will be saturated. This will only lead to increased energy costs.
均熱処理後は熱間圧延を行うが、この熱間圧延に関して
は特に厳密に管理する必要はなく、常法に従って４００
〜５５０℃で加熱して熱間圧延を行えばよい。After the soaking treatment, hot rolling is performed, but there is no need to strictly control this hot rolling.
Hot rolling may be performed by heating at ~550°C.
熱間圧延終了後は、１次冷間圧延を施した後、中間焼鈍

ってもよい。After completion of hot rolling, it is usual to perform first cold rolling, then intermediate annealing, and then final cold rolling.
In some cases, cold rolling may be performed with intermediate annealing performed two or more times.

めには、バッチ焼鈍よりも連続焼鈍を適用することが好
ましい、なお連続焼鈍の場合は中間焼鈍温度を４８０℃
以上にすることがＣｕなとの固溶促進の点でさらに望ま
しい。The appropriate annealing temperature in this intermediate annealing is 300 to 600°C. At temperatures below 300°C, complete recrystallization does not occur;
If the temperature exceeds 0°C, oxidation of the surface becomes intense and the color of the surface changes, which is not preferable. In addition, this intermediate annealing is performed even in one normal batch annealing (average heating rate 20 to 50°C/hr).
Continuous annealing (average heating rate of several degrees Celsius to several tens of degrees Celsius/sec) may be used, but in order to further improve the strength after baking and to make the average recrystallized grain size fine and uniform before final cold rolling, batch annealing is recommended. It is preferable to apply continuous annealing rather than annealing. In the case of continuous annealing, the intermediate annealing temperature should be 480°C.
It is more desirable to do the above from the viewpoint of promoting solid solution with Cu.

After baking for 20 minutes, it was molded into a can end with an outer diameter of 60 mm, and the rivet formability was evaluated. After forming a rivet with an outer diameter of 31 by a three-step stretching process, the tabs were joined, and the presence or absence of rivet cracking at this time was observed. The evaluation of the occurrence of rivet cracking in this test was as follows: Out of 1000 cans molded, those with no cracks were evaluated as ○ (good rivet formability), 1
Those in which ~5 cans were cracked were rated △ (slightly good), and those in which 6 or more cans were cracked were rated × (poor). The results are shown in Table 2.
