Hi, I advise you to look for such materials data in consolidated and proofed databases, like the ones in Ansys Granta softwares. Below a screenshot of typical results you can get searching in the main databases of Granta Selector (MaterialUniverse or JAHM with more than 1500 et 1700 records respectively, for different Al alloys/grades...). You can have access to digitalized stress-strain curves for such metallic materials if required. Regards
