Bending strength (MOR) = low Shearing strength (parallel to grain) = very low Hardness (side grain) = medium Density (dry weight) = 31-37 lbs/cu. ft. Shearing strength (parallel to grain) = low Modulus of Elasticity (stiffness) = low Hardness (side grain) = soft Bending strength (MOR) = high Numerical Data Item Green Dry English Bending Strength 8644 13499 psi Density 37 lbs/ft3 Hardness 1437 lbs Maximum Crushing Strength 3155 5334 psi Shearing Strength 1107 psi Stiffness 1085 1272 1000 psi Weight 36 28 lbs/ft3 Radial Shrinkage 3 % Tangential Shrinkage 9 % Item Green Dry Metric Bending Strength 607 949 kg/cm2 Density 592 kg/m3 Hardness 651 kg Maximum Crushing Strength 221 375 kg/cm2 Shearing Strength 77 kg/cm2 Stiffness 76 89 1000 kg/cm2 Weight 576 448 kg/m3 Radial Shrinkage 3 % References Celulosa Argentina,1973,Libro del Arbol,Celulosa Argentina Buenos Aires 3 Vols Horn, E.F.,1946,New Uses for Brazilian Timbers,Tropical Woods,11(86,pp12-13 Mainieri, C.,1970,Madeiras Brasilieras,Sao Paulo Secretaria da Agricultra, Institulo Florestral Mainieri, C.,1978,Fichas de Caracteristicas das Madeiras Brasileiras,Inst.
