Alloy 1100 is highly resistant to chemical attack and weathering. It is a relatively soft alloy that is very formable and is used extensively in thin gauge and foil products.  It has good welding characteristics and it is also used as a filler alloy for welding purposes.
A desirable characteristic of the alloy is the bright finishes obtained by anodizing.
