Betula pendula
Silver Birch (Betula pendula) is a medium-hardness wood balancing workability and wear resistance, with a Janka hardness of 711 lbf (3163 N) and a density of about 0.61 g/cm³. It originates from europe.
With radial shrinkage of 5.3% and tangential shrinkage of 7.8% (a T/R ratio of 1.47), it is very stable in service, with low risk of cupping or distortion. Its fiber saturation point is around 29%, below which the wood begins to shrink and move as it dries.
