    I remember reading some years ago an article on forging in
    Scientific American. It had detailed pictures of parts made in the
    auto industry that were first cast then forged, by pressing them
    into different sized molds(die struck). Everything was carefully
    calculated to generate maximum strength. It is a multiple step
    process.  Castings are porous, with a larger grain structure, It's
    not just that they bend easier, they wear away faster,  You can
    compensate to some degree with bulking a casting up, but not always.
