Max. crushing strength = high Shrinkage, Radial = large Toughness-Hammer drop (Impact Strength) = very high Toughness-Hammer drop (impact strength) = high Shrinkage, Tangential = fairly large Modulus of Elasticity (stiffness) = very high Modulus of Elasticity (stiffness) = high Hardness (side grain) = very hard Bending strength (MOR) = medium Bending strength (MOR) = high Shrinkage, Tangential = large Shearing strength (parallel to grain) = very high Shearing strength (parallel to grain) = medium Modulus of Elasticity (stiffness) = very low Bending strength (MOR) = low
