Redwood vs Southern Yellow Pine
Natural Material · grade comparison
Redwood and Southern Yellow Pine are both natural material grades. Southern Yellow Pine is the stronger of the two: tensile strength 80 MPa (11.6 ksi) against 70 MPa (10.2 ksi) for Redwood, about 14% more. Southern Yellow Pine is the more ductile: elongation 1.2% versus 1% for Redwood. Redwood is lighter (0.42 g/cm³ vs 0.62 g/cm³ for Southern Yellow Pine) and Southern Yellow Pine is stiffer (11.5 GPa vs 9.6 GPa). On the shop floor, Redwood machines more easily (excellent vs very good) and Southern Yellow Pine sits in a lower cost tier (budget, $) than Redwood (standard, $$).

Southern Yellow PineChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Redwood vs Southern Yellow Pine: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all natural material 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.
