5052-H39 Aluminum Honeycomb vs Aramid Fiber Honeycomb (HRH-49)
Composite · grade comparison
5052-H39 Aluminum Honeycomb and Aramid Fiber Honeycomb (HRH-49) are both composite grades. Aramid Fiber Honeycomb (HRH-49) is the stronger of the two: tensile strength 3 MPa (0.479 ksi) against 3 MPa (0.406 ksi) for 5052-H39 Aluminum Honeycomb, about 18% more. Aramid Fiber Honeycomb (HRH-49) is lighter (0.05 g/cm³ vs 0.05 g/cm³ for 5052-H39 Aluminum Honeycomb) and 5052-H39 Aluminum Honeycomb is stiffer (0.52 GPa vs 0.17 GPa). On the shop floor, 5052-H39 Aluminum Honeycomb sits in a lower cost tier (premium, $$$) than Aramid Fiber Honeycomb (HRH-49) (high, $$$$).
5052-H39 Aluminum HoneycombChoose it when cost is the deciding factor.
Aramid Fiber Honeycomb (HRH-49)Choose it when strength drives the design, or when weight is the constraint.
5052-H39 Aluminum Honeycomb vs Aramid Fiber Honeycomb (HRH-49): 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.
