A. The difference is in the Composition.

AA 1235 is a purer version of aluminium Alloy with low level of Fe & Si used for thin gauge foil rolling. AA 8011 is Al-Fe-Si alloy with high Fe & Si as alloying elements to impart strength in the alloy. AA 8011 is used for slightly higher gauge foil rolling.

Q. Dear sir ,

Can AA 8011 be used for friction stir welding process?

I have not come across any paper in fsw which is using AA8011 as base metal.
