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