Max. crushing strength = high Density (dry weight) = 61-67 lbs/cu. ft Bending strength (MOR) = high Shearing strength (parallel to grain) = low Modulus of Elasticity (stiffness) = high Hardness (side grain) = hard Shrinkage, Tangential = large Shrinkage, Radial = large Density (dry weight) = 53-60 lbs/cu. ft Density (dry weight) = 38-45 lbs/cu. ft. Shrinkage, Tangential = fairly large Shrinkage, Radial = fairly large
