Each number points to the document that states it, with the exact basis. Values without a number are computed from the sourced ones. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
Questions
Mechanical
Which is lighter, Ceramic Aluminum Nitride or Copper C12200?
Ceramic Aluminum Nitride is lighter: 3,400 kg/m³ against 8,941 kg/m³ for Copper C12200.
Which is stiffer, Ceramic Aluminum Nitride or Copper C12200?
Ceramic Aluminum Nitride is stiffer: Young's modulus 320 GPa against 117 GPa for Copper C12200, so the same part in Ceramic Aluminum Nitride deflects less under the same load.
Which is lighter for the same job, Ceramic Aluminum Nitride or Copper C12200?
For the same stiffness or strength: Ceramic Aluminum Nitride is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate.
Part that must be
Ceramic Aluminum Nitride
Copper C12200
Stiff rod or tie (tension)
lighter
7.18x heavier
Stiff beam (bending)
lighter
4.35x heavier
Stiff panel or plate
lighter
3.68x heavier
For the same stiffness or strength, mass scales with density over stiffness (or strength) raised to a power set by how the part is loaded: 1 for a rod in tension, 1/2 for a beam in bending, 1/3 for a panel (the standard material-selection indices).
