Questions Which is lighter, Ceramic Aluminum Nitride or Plastic PEEK? Plastic PEEK is lighter: 1,300 kg/m³ against 3,400 kg/m³ for Ceramic Aluminum Nitride.
Which is stiffer, Ceramic Aluminum Nitride or Plastic PEEK? Ceramic Aluminum Nitride is stiffer: Young's modulus 320 GPa against 4 GPa for Plastic PEEK, 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 Plastic PEEK? 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 Plastic PEEK Stiff rod or tie (tension) lighter 30.6x heavier Stiff beam (bending) lighter 3.42x heavier Stiff panel or plate lighter 1.65x 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).
Which conducts heat better, Ceramic Aluminum Nitride or Plastic PEEK? Ceramic Aluminum Nitride conducts heat better: 150 W/m·K against 0.29 W/m·K for Plastic PEEK.
Which expands less with temperature? Ceramic Aluminum Nitride expands less: 4.6 µm/m·K against 55 µm/m·K for Plastic PEEK.
