Dries flat without splitting Moderately easy to veneer Steam Bending Very poor Painting Good results Polishing Fair to Good Results Satisfactory results Staining Finish is generally satisfactory Strength Properties Density (dry weight) = 31-37 lbs/cu. ft. Density (dry weight) = 38-45 lbs/cu. ft. Shrinkage, Tangential = large Bending strength (MOR) = low Shrinkage, Radial = large Max. crushing strength = medium Hardness (side grain) = very soft Work to Maximum Load = very low Toughness-Hammer drop (Impact Strength) = low Toughness (total work) = low Shrinkage, Radial = moderate Shearing strength (parallel to grain) = very low Shearing strength (parallel to grain) = low Modulus of Elasticity (stiffness) = medium Modulus of Elasticity (stiffness) = low Bending strength (MOR) = medium Numerical Data Item Green Dry English Bending Strength 6911 10833 psi Density 35 lbs/ft3 Hardness 319 lbs Impact Strength 28 inches Maximum Crushing Strength 3916 6397 psi Shearing Strength 1221 psi Stiffness 1511 1745 1000 psi Toughness 167 inch-lbs Work to Maximum Load 5 7 inch-lbs/in3 Weight 34 27 lbs/ft3 Radial Shrinkage 5 % Tangential Shrinkage 10 % Item Green Dry Metric Bending Strength 485 761 kg/cm2 Density 560 kg/m3 Hardness 144 kg Impact Strength 71 cm Maximum Crushing Strength 275 449 kg/cm2 Shearing Strength 85 kg/cm2 Stiffness 106 122 1000 kg/cm2 Toughness 192 cm-kg Work to Maximum Load 0.35 0.49 cm-kg/cm3 Weight 544 432 kg/m3 Radial Shrinkage 5 % References Brown, W.H.,1978,Timbers of the World, No. 2 South America,TRADA, Red Booklet Series Erfurth, T., Rusche, H.,1976,The Marketing of Tropical Wood B.
