Density (dry weight) = 38-45 lbs/cu. ft. Density (dry weight) = 31-37 lbs/cu. ft. Bending strength (MOR) = medium Max. crushing strength = medium Shearing strength (parallel to grain) = low Shrinkage, Tangential = moderate Shrinkage, Radial = moderate Modulus of Elasticity (stiffness) = medium Hardness (side grain) = soft Density (dry weight) = 46-52 lbs/cu. ft. Shrinkage, Radial = fairly large Modulus of Elasticity (stiffness) = low Modulus of Elasticity (stiffness) = high Density (dry weight) = 53-60 lbs/cu. ft. Bending strength (MOR) = high Work to Maximum Load = very low Shrinkage, Tangential = small Shrinkage, Tangential = fairly large Shrinkage, Radial = small Shearing strength (parallel to grain) = very low Max. crushing strength = high Heavy Hardness (side grain) = hard Density = high Compression strength (parallel to grain) = high Bending strength (MOR) = very low
