Density (dry weight) = 38-45 lbs/cu. ft. Density (dry weight) = 46-52 lbs/cu. ft. Shearing strength (parallel to grain) = high Modulus of Elasticity (stiffness) = medium Max. crushing strength = medium Hardness (side grain) = medium Density (dry weight) = 31-37 lbs/cu. ft. Bending strength (MOR) = medium Shrinkage, Tangential = moderate Shrinkage, Tangential = large Shrinkage, Tangential = fairly large Shrinkage, Radial = small Shrinkage, Radial = moderate Shrinkage, Radial = fairly large High in density Hardness = medium Compression strength (parallel to grain) = high
Resistant to wearing and marring
The bending strength of air-dried wood of the species is similar to that of Teak, which is considered to be strong. Other species in this range include Teak, White oak, and Hard maple (for high compression parallel to grain).
