Bending strength (MOR) = high Modulus of Elasticity (stiffness) = medium Max. crushing strength = high Density (dry weight) = 46-52 lbs/cu. ft. Work to Maximum Load = low Shearing strength (parallel to grain) = medium Hardness (side grain) = medium Toughness (total work) = low Shrinkage, Radial = very small Shrinkage, Radial = large Shrinkage, Radial = fairly large Density (dry weight) = 38-45 lbs/cu. ft.
Species has very high bending strength, and is much stronger than Teak in the air-dry condition (about 12 percent moisture content). It has superior properties in compression parallel to grain in the air-dry condition than Teak, White oak, or Hard maple. Hardness is rated as medium. It resists denting and marring about as well as white oak or birch. It is a heavy wood. The wood has high density.
