Composition of aluminum running boards

[CV66]

Would anyone know what composition of aluminum the off-road running boards are made of?

You want to know what alloy is involved, my guess is because you cracked one and want to weld a repair?

Ok, now that a few others have chimed in..........I didn't want to smart off right off the bat....

Recycled Bush beer cans?

Probably 300 or 700 series alloys, don't know the exact alloy used but these are very common series for
sand casting. Think a shop that does aircraft structural repairs may be able to help.
