I saw the strangest thing ever on Wednesday...Aluminium welded with steel.

!
My brother has a small sample of brass welded to aluminium (i.e. no glue). Apparently he got it from a firm specialising in 'explosive' welding ????

Not new, some years ago there was interest in steel sheet with a copper (or may have been nickel)layer explosively weled for ships hulls not heard of it lately supposed to make the ships cheaper to run by reducing marine growths.
