Density (dry weight) = 31-37 lbs/cu. ft. Bending strength (MOR) = medium Shrinkage, Tangential = moderate Shrinkage, Radial = moderate Modulus of Elasticity (stiffness) = medium Max. crushing strength = medium Bending strength (MOR) = very high Bending strength (MOR) = high Numerical Data Item Green Dry English Bending Strength 13276 19839 psi Density 36 lbs/ft3 Maximum Crushing Strength 3916 6397 psi Stiffness 1665 1923 1000 psi Weight 35 28 lbs/ft3 Radial Shrinkage 4 % Tangential Shrinkage 7 % Item Green Dry Metric Bending Strength 933 1394 kg/cm2 Density 576 kg/m3 Maximum Crushing Strength 275 449 kg/cm2 Stiffness 117 135 1000 kg/cm2 Weight 560 448 kg/m3 Radial Shrinkage 4 % References Brown, W.H.,1978,Timbers of the World, No. 9 Central America and the Caribbean,TRADA, Red Booklet Series Erfurth, T., Rusche, H.,1976,The Marketing of Tropical Wood B.
