I can tell you that the material that you use has a lot to do with the
properties of a structure.  Those of us who study materials have very
specific terms for the different properties that you might think are the
same, like stiffness, strength, toughness and hardness.  Generally, metals
are very tough, can have good strength and stiffness but are not very hard. 
Ceramics are very hard and stiff but not very tough.  Plastics are strong
(sometimes) and tough, but not hard or stiff.
