Questions
Is Magnesium AZ31B-H24 stronger than Plastic LCP GF30?
Magnesium AZ31B-H24 is stronger: its yield strength is 220 MPa against tensile strength 115 MPa for Plastic LCP GF30 (1.91x).
Which is lighter, Magnesium AZ31B-H24 or Plastic LCP GF30?
Plastic LCP GF30 is lighter: 1,610 kg/m³ against 1,769 kg/m³ for Magnesium AZ31B-H24.
Which is stiffer, Magnesium AZ31B-H24 or Plastic LCP GF30?
Magnesium AZ31B-H24 is stiffer: Young's modulus 44.8 GPa against 11.5 GPa for Plastic LCP GF30, so the same part in Magnesium AZ31B-H24 deflects less under the same load.
Which is lighter for the same job, Magnesium AZ31B-H24 or Plastic LCP GF30?
For the same stiffness or strength: Magnesium AZ31B-H24 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.
Part that must be

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, Magnesium AZ31B-H24 or Plastic LCP GF30?
Magnesium AZ31B-H24 conducts heat better: 76.9 W/m·K against 0.5 W/m·K for Plastic LCP GF30.
Which expands less with temperature?
Plastic LCP GF30 expands less: 20 µm/m·K against 26.8 µm/m·K for Magnesium AZ31B-H24.
