Bending strength (MOR) = medium 0 Max. crushing strength = medium Max. crushing strength = high Density (dry weight) = 61-67 lbs/cu. ft Density (dry weight) = 53-60 lbs/cu. ft Shrinkage, Tangential = fairly large Shrinkage, Radial = small Shearing strength (parallel to grain) = high Modulus of Elasticity (stiffness) = high Density (dry weight) = 46-52 lbs/cu. ft. Shrinkage, Tangential = large Shrinkage, Radial = fairly large Bending strength (MOR) = high Shrinkage, Tangential = small Shrinkage, Radial = very small Shrinkage, Radial = large Shearing strength (parallel to grain) = low Modulus of Elasticity (stiffness) = very low Modulus of Elasticity (stiffness) = medium Hardness (side grain) = hard Density (dry weight) = 67-75 lbs/cu.ft Bending strength (MOR) = low Shrinkage, Tangential = moderate Shrinkage, Radial = moderate Shearing strength (parallel to grain) = very high Modulus of Elasticity (stiffness) = low Hardness (side grain) = very hard
