Quercus robur
European Oak (Quercus robur) is a medium-hardness wood balancing workability and wear resistance, with a Janka hardness of 742 lbf (3300 N) and a density of about 0.67 g/cm³. It originates from europe.
With radial shrinkage of 4.6% and tangential shrinkage of 9% (a T/R ratio of 1.96), it is reasonably stable with normal seasonal movement. Its fiber saturation point is around 28%, below which the wood begins to shrink and move as it dries.
