Maybe you should reach out to these guys, they are currently working on the same problem.

But why? Latent heat of aluminum is so high as it is, and the conductivity is so high... why would you choose aluminum? You could likely add cooling to your part.

Otherwise time to look at titanium. Aluminum isn't a hot working material.
