Because aluminum has a higher value of thermal conductivity than stainless steel by a factor of 7.

For aluminum k=1400 btu-in/hr-sq.ft-deg.F

For stainless steel k=200btu-in/hr-sq.ft.-deg.F

aluminum's heat index is lower than that of stainless steel.

It could be that aluminium has a lower heat capacity or just that it is less dense and therefore has less mass (for the same sized pan/object) to heat.
