    "Pot metal" is a near random mix of metals (mostly white metals),
    such as aluminium, zinc, tin, copper (sometimes), magnesium etc. And
    it is called pot metal because the way it was made was that what ever
    they had was chucked in the pot and used. The alloy is just a random
    mix and will vary item to item...... 

    It can be soldered (use aluminium solders and fluoride fluxes),
    sometimes it will take to brazing, but this is quite rare as the
    melting temp of a typical pot metal is usually quite low (say between
    450'C and 660'C). Other than that you might be able to laser weld it,
    but I don't know what you'd use for filler wire. 

Good luck.
Thomas.
