Just in case anyone finds a beryllium brick somewhere and tries to
use it:
Beryllium is very very poisonous.

Looking at the specific heat of metals:

Wouldn't Beryllium be better instead of aluminium?
I could foresee a few problems though eg machining holes at home,
never mind where to get a block from.

Actually in this application minimising the volume of the metal
block rather than its weight is probably better so one should use
specific heat*density as a figure of merit.
METAL Specific heat*density (W/J/cubic cm)
Aluminium 2.46
Beryllium 3.29
Copper 3.49
Silver 2.41
Iron 3.87
Thus copper and iron are better choices than Beryllium they also
poses fewer machining diffculties
