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