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, Aluminum 3003-O or Ceramic Aluminum Nitride?
Aluminum 3003-O is lighter: 2,730 kg/m³ against 3,400 kg/m³ for Ceramic Aluminum Nitride.
Which is stiffer, Aluminum 3003-O or Ceramic Aluminum Nitride?
Ceramic Aluminum Nitride is stiffer: Young's modulus 320 GPa against 69 GPa for Aluminum 3003-O, so the same part in Ceramic Aluminum Nitride deflects less under the same load.
Which is lighter for the same job, Aluminum 3003-O or Ceramic Aluminum Nitride?
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.
