Shearing strength (parallel to grain) = medium Density (dry weight) = 53 - 60 lbs/cu. ft. Density (dry weight) = 46-52 lbs/cu. ft. Modulus of Elasticity (stiffness) = medium Modulus of Elasticity (stiffness) = low Max. crushing strength = medium Max. crushing strength = high Hardness (side grain) = soft Hardness (side grain) = medium Bending strength (MOR) = medium Bending strength (MOR) = high
