Density (dry weight) = 67-75 lbs/cu. ft. Work to Maximum Load = low Modulus of Elasticity (stiffness) = very high Density (dry weight) = 61 - 67 lbs/cu. ft. Hardness (side grain) = very hard Bending strength (MOR) = very high Modulus of Elasticity (stiffness) = medium Modulus of Elasticity (stiffness) = low Max. crushing strength = very high Max. crushing strength = high Density (dry weight) = 53 - 60 lbs/cu. ft. Shrinkage, Tangential = large Shrinkage, Radial = large Hardness (side grain) = hard Bending strength (MOR) = high
