Radiata Pine vs Redwood
Natural Material · grade comparison
Radiata Pine and Redwood are both natural material grades. Radiata Pine is the stronger of the two: tensile strength 90 MPa (13.1 ksi) against 70 MPa (10.2 ksi) for Redwood, about 29% more. Redwood is lighter (0.42 g/cm³ vs 0.48 g/cm³ for Radiata Pine) and Radiata Pine is stiffer (10.2 GPa vs 9.6 GPa). On the shop floor, Radiata Pine sits in a lower cost tier (budget, $) than Redwood (standard, $$).
Radiata PineChoose it when strength drives the design, or when the part sees heat.
RedwoodChoose it when weight is the constraint.
Radiata Pine vs Redwood: 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.
