Aluminum or Steel?

The argument aluminum tool makers have been using for years is aluminum is a better conductor of heat.  This part is true, and due to this cycle times to produce a part are shorter.  This part is true as well, when comparing the same thickness of material.  But due to the strength of steel vs. aluminum you are able to use much thinner material and have a stronger mould with cycle times and heat transfer that are even.
