Hello Soni,

You can find some properties for pure aluminum in the attached snapshot and link below.

Best of luck!

Hello Bhasker Soni, here is what I found:

Young's modulus

70 GPa

Thin Solid Films,270(1995), p.263

you know Al doesn't has a clear yield Point hence the 0.2% strain Limit is used instead which result for more or less Pure aluminum to about 47 MPa  / for Films to about  70 MPa.
