Questions

Is Aluminum 1100-O stronger than Aluminum 5052-H32?

Aluminum 5052-H32 is stronger: its yield strength is 195 MPa against 35 MPa for Aluminum 1100-O (5.57x).

Which is lighter, Aluminum 1100-O or Aluminum 5052-H32?

Aluminum 5052-H32 is lighter: 2,685 kg/m³ against 2,710 kg/m³ for Aluminum 1100-O.

Which is stiffer, Aluminum 1100-O or Aluminum 5052-H32?

Aluminum 5052-H32 is stiffer: Young's modulus 70 GPa against 69 GPa for Aluminum 1100-O, so the same part in Aluminum 5052-H32 deflects less under the same load.

Which is lighter for the same job, Aluminum 1100-O or Aluminum 5052-H32?

For the same stiffness or strength: Aluminum 5052-H32 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	Aluminum 1100-O	Aluminum 5052-H32
Stiff rod or tie (tension)	2% heavier	lighter
Stiff beam (bending)	2% heavier	lighter
Stiff panel or plate	1% heavier	lighter
Strong rod or tie	5.62x heavier	lighter
Strong beam	3.17x heavier	lighter
Strong panel or plate	2.38x heavier	lighter

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, Aluminum 1100-O or Aluminum 5052-H32?

Aluminum 1100-O conducts heat better: 222 W/m·K against 138 W/m·K for Aluminum 5052-H32.

Which expands less with temperature?

Aluminum 1100-O expands less: 23.6 µm/m·K against 23.8 µm/m·K for Aluminum 5052-H32.
