1. A method of manufacturing a heat transfer apparatus from first and second materials which are characterized by first and second melting temperatures, respectively, and, wherein, the first and second materials alloy at a lower temperature than each of the first and second temperatures, the method comprising the steps of:

  • forming a conduit construction including a first portion from the first material, the first portion forming a passageway which traverses the distance between a first construction end and a second construction end;

    coating the first portion with a binder material, the binder material operating as a barrier to alloying between the first and second materials;

    disposing the first portion in a mold cavity such that the first and second ends are located outside the cavity;

    introducing the second material in molten fluid form into the cavity so as to cover the first portion; and

    permitting the molten second material to solidify.
