Elsewhere, someone has just claimed that fan-assisted ovens have
aluminium elements. My immediate reaction was "Of course they don't".
But then I realised that I really don't know what the elements are made
from.

So - what is the outer casing of typical electric elements such as these
made from? Could any be made from aluminium? Maybe there is even some
sort of "heatsink" (can't think what else they'd be called - so
terminology from a PC seems reasonable!) that isn't the element itself.
