Aluminum-based alloy

[0036] Samples were produced under the same conditions as in the first example except that an aging treatment was performed at 90° C. for 10 days, and the Young’s modulus was measured. The results are shown in Table 2. In addition, the Young's modulus calculated using the above-mentioned formula 1 is collectively recorded in Table 2.

[0037] [Table 2]

[0038]

[0039] As shown in Table 2, the Young's modulus calculated using the formula 1 is very close to the measured value, confirming the correctness of the selection of Cu, Zn, Ag, and Li.

[0040] 3. The third embodiment

[0041] In addition to ingredients and aging treatment conditions are figure 2 Except for the cases shown, aluminum-based alloy samples were produced under the same conditions as those in the first example. according to figure 2 It can be seen that when the aging temperature is 170° C., a Young's modulus of 77 GPa or more can be obtained by aging for 240 hours. It was also confirmed that, when ...
