5056 Aluminum Honeycomb vs Cross-linked PVC Foam Core
Composite · grade comparison
5056 Aluminum Honeycomb and Cross-linked PVC Foam Core are both composite grades. 5056 Aluminum Honeycomb is the stronger of the two: tensile strength 4 MPa (0.624 ksi) against 3 MPa (0.363 ksi) for Cross-linked PVC Foam Core, about 72% more. 5056 Aluminum Honeycomb is lighter (0.05 g/cm³ vs 0.08 g/cm³ for Cross-linked PVC Foam Core) and 5056 Aluminum Honeycomb is stiffer (1 GPa vs 0.1 GPa). On the shop floor, Cross-linked PVC Foam Core machines more easily (excellent vs fair) and Cross-linked PVC Foam Core sits in a lower cost tier (premium, $$$) than 5056 Aluminum Honeycomb (high, $$$$).
5056 Aluminum HoneycombChoose it when strength drives the design, or when weight is the constraint.
Cross-linked PVC Foam CoreChoose it when the part is machined in volume, or when cost is the deciding factor.
5056 Aluminum Honeycomb vs Cross-linked PVC Foam Core: 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.
