Shearing strength (parallel to grain) = low Max. crushing strength = medium Bending strength (MOR) = medium Modulus of Elasticity (stiffness) = medium Density (dry weight) = 31-37 lbs/cu. ft. Hardness (side grain) = soft Shrinkage, Radial = small Shrinkage, Tangential = small Modulus of Elasticity (stiffness) = low Density (dry weight) = 38-45 lbs/cu. ft. Shrinkage, Tangential = moderate Bending strength (MOR) = low Shrinkage, Tangential = very small Shrinkage, Tangential = fairly large Shrinkage, Radial = very small Shrinkage, Radial = moderate Density (dry weight) = 23-30 lbs/cu. ft. Compression strength (parallel to grain) = high
The bending strength of air-dried wood of the species is similar to that of Teak, which is considered to be strong. Strength in compression parallel to grain is in the high range. Other species in this range include Teak, White oak, and Hard maple. The weight is high. The density is high.
