5052-H39 Aluminum Honeycomb 5.7-1/8-.0015 vs 5052-H39 Aluminum Honeycomb CR
Composite · 5052-H39 Aluminum Honeycomb grade comparison
5052-H39 Aluminum Honeycomb 5.7-1/8-.0015 and 5052-H39 Aluminum Honeycomb CR are two grades of the same composite grade, 5052-H39 Aluminum Honeycomb: 5.7-1/8-.0015 (5.7 pcf) versus CR (cold rolled). The chemistry is identical, so every difference below comes from the condition. 5052-H39 Aluminum Honeycomb 5.7-1/8-.0015 is the stronger of the two: yield strength 3 MPa (0.471 ksi) against 1 MPa (0.189 ksi) for 5052-H39 Aluminum Honeycomb CR, about 150% more; tensile strength follows at 7 MPa (0.957 ksi) vs 2 MPa (0.276 ksi). 5052-H39 Aluminum Honeycomb CR is lighter (0.05 g/cm³ vs 0.09 g/cm³ for 5052-H39 Aluminum Honeycomb 5.7-1/8-.0015) and 5052-H39 Aluminum Honeycomb 5.7-1/8-.0015 is stiffer (1.4 GPa vs 0.52 GPa). On the shop floor, 5052-H39 Aluminum Honeycomb 5.7-1/8-.0015 machines more easily (50 vs 38 out of 100).
5052-H39 Aluminum Honeycomb 5.7-1/8-.0015Choose it when strength drives the design, or when the part is machined in volume.
5052-H39 Aluminum Honeycomb CRChoose it when weight is the constraint.
5052-H39 Aluminum Honeycomb 5.7-1/8-.0015 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.
