Bending strength (MOR) = medium Max. crushing strength = high Hardness (side grain) = soft Shrinkage, Tangential = fairly large Shrinkage, Radial = very small Max. crushing strength = medium Shrinkage, Volumetric = fairly large Shrinkage, Tangential = moderate Shrinkage, Radial = fairly large Shearing strength (parallel to grain) = low Modulus of Elasticity (stiffness) = medium Modulus of Elasticity (stiffness) = low Bending strength (MOR) = low Bending strength (MOR) = high
