Perhaps, but Ti melts at over 1000 degrees C higher than aluminum, 1668C (3034F) vs 660C (1220F), so the Ti would just get strained out as solid chunks after the aluminum has melted and been poured off. It is this property that allows Mach 3 and 4 aircraft to be made from titanium, whereas aluminum aircraft are limited to a little over Mach 2.
