Bending strength (MOR) = low Density (dry weight) = 31-37 lbs/cu. ft. Modulus of Elasticity (stiffness) = very low Max. crushing strength = medium Max. crushing strength = low Shrinkage, Tangential = small Shrinkage, Radial = very small Shearing strength (parallel to grain) = very low Density (dry weight) = 23-30 lbs/cu. ft. Work to Maximum Load = very low Shrinkage, Tangential = very small Shrinkage, Radial = small Hardness (side grain) = very soft Surfaces may dent or scratch easily Shrinkage, Tangential = moderate Shearing strength (parallel to grain) = low Density = high Compression strength (parallel to grain) = medium Bending strength (MOR) = high
