Density (dry weight) = 53-60 lbs/cu. ft 1 Modulus of Elasticity (stiffness) = low Max. crushing strength = high Shrinkage, Tangential = large Shrinkage, Tangential = fairly large Shrinkage, Radial = large Shrinkage, Radial = fairly large Hardness (side grain) = very hard Hardness (side grain) = hard Density (dry weight) = 46-52 lbs/cu. ft. Bending strength (MOR) = high Shrinkage, Tangential = moderate Shrinkage, Radial = moderate Shearing strength (parallel to grain) = very high Shearing strength (parallel to grain) = low Modulus of Elasticity (stiffness) = medium Max. crushing strength = medium Density (dry weight) = 61-67 lbs/cu. ft Bending strength (MOR) = medium Bending strength (MOR) = low
