Mor/Bending strength = low Hardness (side grain) = soft Density (dry weight) = 31-37 lbs/cu. ft. Density (dry weight) = 31-37 lbs/cu. ft. Modulus of Elasticity (stiffness) = very low Medium Max. crushing strength = low 38-45 lbs/cu. ft. 38-45 lbs/cu. ft. Shrinkage, Radial = moderate Shearing strength (parallel to grain) = very low Low
