No need to replace the seat tube. The aluminum will melt long before the brass or silver starts to liquefy. Aluminum is an excellent conductor of heat, so once it reaches its melting point, the whole thing melts, all at once. Position the frame upside-down with the seat tube directly over a metal bucket of water -- you *DON'T* want that blob of molten aluminum to hit the floor and splatter when it goes!
