Heartwood Color Pale red to pink Greenish to greyish Pink grey Golden brown with a reddish cast Darkens upon exposure Brown Sapwood Color Color not distinct from heartwood Paler than heartwood Grain Interlocked Figure Rays (figure) Weak (figure) Texture Fine Very fine Even textured Luster Dull Slightly lustrous Non-lustrous Lustrous Natural Durability Non durable Sapwood is susceptible to wood staining fungal attack Susceptible to attack from termites (Isoptera) Susceptible to marine borer attack Susceptible to attack by marine borers and termites Sapwood prone to stain Resistant to attack from powder post (Lyctid & Bostrychid) beetles Perishable Odor No specific smell or taste Silica Content Contains silica Resin Content Contains resin Machining operations may be affected by resins. Light-Induced Color Change Darker Toxicity Sap from bark can cause severe itching and urticaria in some individuals Dermatitic effects A chemical is contained in sap from tha bark which can cause severe itching and urticaria in some Kiln Schedules Drying (speed) is fast Drying Defects No surface checking Moderate spring/bow Special attention required Slight spring/bow Sapwood liable to stain No end splitting Moderate end spitting Moderate cupping Use proper precautions to prevent splitting and bowing Ease of Drying Special attention required Little degrade if dried properly Easy Dries at a fairly rapid rate Weight down stacks to minimize degrade Tree Identification Bole/stem form is buttressed Comments Abnormal Wood Tissue - Reaction wood, which can adversely affect machining and other properties may be present. Reaction wood may be present Blunting Effect Slight effect Blunting effect on machining is slight Boring Easy Cutting Resistance Cutting Resistance with dry wood is easy Cutting Resistance with dry wood is difficult Low resistance Cutting Resistance with green wood is easy Fine resinous sawdust may clog saw teeth Nailing Holds nails well Planing Does not plan to a good finish Easy to plane Tension in wood may result in woolly quartersawn surfaces. Planed surfaces are without luster Resistance to Impregnation Heartwood is permeable Heartwood is moderately resistant Sapwood is moderately treatable Resistance to Splitting Good Turning Turning qualities are poor Easy to turn Veneering Qualities Easy to cut Strength Properties Density (dry weight) = 23-30 lbs/cu. ft. Shrinkage, Tangential = very small Weight = light Toughness-Hammer drop (Impact Strength) = very low Surfaces may dent or scratch easily Surfaces may dent easily Shrinkage, Volumetric = small Shrinkage, Tangential = small Max. crushing strength = low Hardness (side grain) = very soft Compression strength (parallel to grain) = low Bending strength (MOR) = low Bending strength of the species in the air-dry condition (about 12 percent moisture content) is considered low - much lower than Teak, for example. Maximum crushing strength, or compression strength parallel to grain, is low. It is weaker than Mahogany or Teak. The wood is soft, and surfaces may dent easily. It also does not wear well, and mars easily. The wood is light in weight. The density is average, or medium Numerical Data Item Green Dry English Bending Strength 4343 6004 psi Crushing Strength 172 314 psi Density 24 lbs/ft3 Hardness 327 lbs Impact Strength 13 15 inches Maximum Crushing Strength 2210 3624 psi Shearing Strength 1076 psi Static Bending 2322 3119 psi Stiffness 813 1000 1000 psi Work to Maximum Load 4 5 inch-lbs/in3 Specific Gravity 0.26 0.28 Weight 24 21 lbs/ft3 Radial Shrinkage 2 % Tangential Shrinkage 5 % Volumetric Shrinkage 8 % Item Green Dry Metric Bending Strength 305 422 kg/cm2 Crushing Strength 12 22 kg/cm2 Density 384 kg/m3 Hardness 148 kg Impact Strength 32 38 cm Maximum Crushing Strength 155 254 kg/cm2 Shearing Strength 75 kg/cm2 Static Bending 163 219 kg/cm2 Stiffness 57 70 1000 kg/cm2 Work to Maximum Load 0.28 0.35 cm-kg/cm3 Specific Gravity 0.26 0.28 Weight 384 336 kg/m3 Radial Shrinkage 2 % Tangential Shrinkage 5 % References Desch, H.E. 1957.
