OCXO housings - Why copper and not iron/steel?

And (if I remember the numbers properly) Isotopically pure diamond has twice the thermal conductivity of natural diamond.  There are places that make diamond-like carbon thermal pads.  Also places that make actual diamond ones (which are not as expensive as you would think),


Actually, diamond has five times better thermal conductivity than silver,

so is the most conductive element, although graphene is suspected to be
better still.

And for the serious low-noise enthusiast, a side benefit of cooling to
cryogenic
temperatures like 15K or so is that the thermal conductivity of copper is
something
like 25X what it is at room temperature.
