Have you figured in the difference in thermal conductivity between Al and Ti?
What's the mechanism for that being relevant? The metal case is very thin, so the heat transfer from inside to outside will be dominated by shape (for conduction) and colour (for radiation). To the extent that it's relevant, Al (even alloy) is a far better heat conductor than Ti, which is probably going to make it less efficient dues to wastage to the surroundings.

I’m guessing, based on carrying my Ti bike and my sons Al one on cold days, that an Aluminium kettles are more efficient.
