With specific heats of 0.91 kcal/(kg⋅K) for aluminium and 0.46 kcal/(kg⋅K) for cast iron, this works out to
Aluminium: ~2500 kcal/(kg⋅m³)
Cast iron: ~3100 - 3600 kcal/(kg⋅m³)
So for a pan of the same thickness/shape, cast iron should have a heat capacity that's 25-45% higher.
- balfirevic 5y agoWhen using pans, I don't particularly care if they are too thick bit I do care if they are too heavy. Aluminium pan could be lighter while having equal or greater heat capacity, if it were thick enough. I don't know if such thick aluminium pans are available, though.
- 8note 5y agoIt's not just the weight that you'll care about, it's also the moment of inertia, which will help/hinder your ability to reorient the pan
