5052-H39 Aluminum Honeycomb 2.3-3/16-.0007 vs 5052-H39 Aluminum Honeycomb CR
Composite · 5052-H39 Aluminum Honeycomb grade comparison
5052-H39 Aluminum Honeycomb 2.3-3/16-.0007 and 5052-H39 Aluminum Honeycomb CR are two grades of the same composite grade, 5052-H39 Aluminum Honeycomb: 2.3-3/16-.0007 (2.3 pcf) versus CR (cold rolled). The chemistry is identical, so every difference below comes from the condition. 5052-H39 Aluminum Honeycomb CR is the stronger of the two: yield strength 1 MPa (0.189 ksi) against 0.83 MPa (0.12 ksi) for 5052-H39 Aluminum Honeycomb 2.3-3/16-.0007, about 57% more; tensile strength follows at 2 MPa (0.276 ksi) vs 2 MPa (0.261 ksi). 5052-H39 Aluminum Honeycomb 2.3-3/16-.0007 is lighter (0.04 g/cm³ vs 0.05 g/cm³ for 5052-H39 Aluminum Honeycomb CR) and 5052-H39 Aluminum Honeycomb CR is stiffer (0.52 GPa vs 0.31 GPa).

5052-H39 Aluminum Honeycomb 2.3-3/16-.0007 vs 5052-H39 Aluminum Honeycomb CR: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all composite grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
