Bending strength (MOR) = medium Max. crushing strength = medium Density (dry weight) = 38-45 lbs/cu. ft. Bending strength (MOR) = high Modulus of Elasticity (stiffness) = medium Hardness (side grain) = medium Density = high Compression strength (parallel to grain) = high Bending strength (MOR) = very low
It is far superior in strength to either Teak or Hard maple
