It is also cultivated for its edible fruits and as a source of honey in several tropical areas.

Resistance to Impregnation Heartwood is permeable Heartwood is highly resistant Absorption is fair to good Response to Hand Tools Easy to Work Easy to machine Sanding Very Good to Excellent Results Fair to Good Results Polishing Fair to Good Results Very Good to Excellent Results Staining Fair to Good Results Very Good to Excellent Results Strength Properties Modulus of Elasticity (stiffness) = very low Max. crushing strength = low Bending strength (MOR) = very low Density (dry weight) = 23-30 lbs/cu. ft. Weight = light Shrinkage, Tangential = fairly large Shrinkage, Radial = small Resistance to denting and marring is low Hardness (side grain) = very soft Hardness (side grain) = soft Density (dry weight) = 31-37 lbs/cu. ft. Compression strength (parallel to grain) = low Bending strength (MOR) = low Numerical Data Item Green Dry English Bending Strength 3510 5403 psi Crushing Strength 255 343 psi Density 27 lbs/ft3 Hardness 427 lbs Maximum Crushing Strength 2161 4113 psi Shearing Strength 715 psi Static Bending 3009 4557 psi Stiffness 1009 1199 1000 psi Toughness 47 inch-lbs Work to Maximum Load 2 3 inch-lbs/in3 Specific Gravity 0.37 Weight 25 23 lbs/ft3 Radial Shrinkage 3 % Tangential Shrinkage 7 % Volumetric Shrinkage 9 % Item Green Dry Metric Bending Strength 246 379 kg/cm2 Crushing Strength 17 24 kg/cm2 Density 432 kg/m3 Hardness 193 kg Maximum Crushing Strength 151 289 kg/cm2 Shearing Strength 50 kg/cm2 Static Bending 211 320 kg/cm2 Stiffness 70 84 1000 kg/cm2 Toughness 54 cm-kg Work to Maximum Load 0.14 0.21 cm-kg/cm3 Specific Gravity 0.37 Weight 400 368 kg/m3 Radial Shrinkage 3 % Tangential Shrinkage 7 % References Chudnoff, M.,1984,Tropical Timbers of the World,U.S.A.
