Questions

Which is lighter, Ceramic Aluminum Nitride or Plastic LCP GF30?

Plastic LCP GF30 is lighter: 1,610 kg/m³ against 3,400 kg/m³ for Ceramic Aluminum Nitride.

Which is stiffer, Ceramic Aluminum Nitride or Plastic LCP GF30?

Ceramic Aluminum Nitride is stiffer: Young's modulus 320 GPa against 11.5 GPa for Plastic LCP GF30, 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 LCP GF30?

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 beCeramic Aluminum NitridePlastic LCP GF30
Stiff rod or tie (tension)lighter13.2x heavier
Stiff beam (bending)lighter2.5x heavier
Stiff panel or platelighter43% 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 LCP GF30?

Ceramic Aluminum Nitride conducts heat better: 150 W/m·K against 0.5 W/m·K for Plastic LCP GF30.

Which expands less with temperature?

Ceramic Aluminum Nitride expands less: 4.6 µm/m·K against 20 µm/m·K for Plastic LCP GF30.
