Chamaecyparis cedars
Hardness among the 3 chamaecyparis cedars here ranges from 350 lbf (Atlantic white-cedar) to 630 lbf (Port-Orford-cedar). The flattest-drying is Port-Orford-cedar; the stiffest is Port-Orford-cedar.
- Its median hardness, 580 lbf, is 16% above the median for U.S. softwoods.
- One of the three is in the softest quarter of the 155 woods (up to 565 lbf); the rest sit in the middle half.
- Density runs from a specific gravity of 0.31 in Atlantic white-cedar to 0.42 in yellow-cedar.
- The stiffest is Port-Orford-cedar, at 1.70 million psi, 72nd of all 155.
- 580 lbfmedian hardness
- 0.39median density
- 11,100 psimedian bending strength
- 6.0%median face shrinkage
