Diamond:
Best material for maximising merit index E /ρ, and hence good for loading a beam in tension to minimise deflection, and for bending a beam of free width to minimise deflection.

Butyl:
Worst material for maximising merit index E /ρ, and hence poor for loading a beam in tension to minimise deflection, and for bending a beam of free height to minimise deflection.
