Metals question - melting bismuth onto aluminum

  1. Sep 8, 2011 #1
    hey guys, i am planning on buying some pieces of bismuth, as well as machining a disc of aluminum so that there is a hollow circular 'canal' which goes concentric on the disc

    aluminum has a melting point of 660.32 degrees celcius, for bismuth it is 271.5 degrees celcius

    i also have a very powerful blowtorch ...

    is it possible to simply dump the bismuth pieces into the 'canal' , melt them and then let them fill up the 'canal' ? will molten bismuth do anything to aluminum?

    most importantly, will aluminum do anything to molten bismuth which will affect the diamagnetic effect of bismuth, since it is part of a magnetic levitation setup i am trying to build
