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