Yeah, but there has to be more to it than that.  Gray cast iron is a
great material for machine bases, etc., because it damps (not "dampens")
the vibrations.

	Well, I'll take a stab at it by saying that within
	limits, higher rigidity reduces dampening effects.
	Materials such as lead have a high tendency to dampen
	vibration, which is one of the reasons it is used in
	dead blow hammers.  The low elasticity of the material
	very effectively dampens the blow such that the energy
	dissipates into the work.  With higher rigidity comes
	(usually) higher elasticity, which dissipates energy
	in the body of bell a lot less, leaving more to dissipate 
	into the air, which produces more sound.
