Max. crushing strength = medium Hardness (side grain) = soft Density (dry weight) = 31-37 lbs/cu. ft. Bending strength (MOR) = medium Shrinkage, Tangential = very small Shrinkage, Radial = very small Shearing strength (parallel to grain) = low Bending strength (MOR) = low Bending strength (MOR) = high Toughness-Hammer drop (Impact Strength) = very low Toughness-Hammer drop (Impact Strength) = low Shrinkage, Tangential = small Shrinkage, Tangential = moderate Shrinkage, Radial = small Shrinkage, Radial = large Modulus of Elasticity (stiffness) = very low Modulus of Elasticity (stiffness) = low Medium weight High in density Hardness = medium Density (dry weight) = 38-45 lbs/cu. ft. Compression strength (parallel to grain) = medium
It compares favorably with Teak, which also has high bending strength.It resists denting and marring about as well as white oak or birch
