I still find brass interesting (my first thermal die sim was brass, but later versions have all been copper)

+Thermal conductivity similar to silicon
+Tougher than copper (more robust surface area)
+Easy to machine, readily available
+Relatively good thermal conductivity
- Main body will run much hotter for a given die surface temp than copper, especially when incorporating a calorimeter tower section. This will produce much greater heat loss to ambient. Can be easily accounted for though by running a heat loss calibration curve.
