Batong Buhay , Sablayan ,  Occidental Mindoro) Heartwood Color Yellow Brown Yellowish to greenish Greenish to greyish Faint streaks occasionally Dark brown with black bands Brown walnut Heartwood often has irregular concentric dark brown to black bands or fine streaks Sapwood Color Brown Yellow Wide Pinkish Pale yellow Grey Clearly differentiated from the heartwood Grain Even Figure Irregular Straight Interlocked Straight to interlocked Irregular Texture Fine Even or uniform Uniform Medium coarse to coarse Luster Lustrous Natural Durability Perishable Non-durable Susceptible to attack by marine borers and termites Resistance varies Natural resistance to decay is reported to depend largely upon origin of species. Material from New Guinea is more resistant to attack by decay fungi Odor Has an odor No specific smell or taste Drying Defects Weighting of stacks is recommended May warp and twist during drying Ease of Drying Slowly Moderately Difficult to Difficult Little degrade if dried properly Fairly difficult to dry Dry slowly and carefully to minimize degrade Tree Size Bole length is 20-30 m Tree height is 30-40 m Product Sources The trees are reported to occur in small numbers in the forests, and are seldom harvested for lumber. Comments Reaction Wood - Some logs are reported to contain tension wood. Blunting Effect Slight dulling effect on cutting tools Boring Fair to good results Responds well to both hand and machine tools in boring and all woodworking operations Easy Carving Fair to Good Results Very Good to Excellent Results Cutting Resistance Easy to saw Easy to saw The wood has low resistance to cutting, and saws rather readily Gluing Fair to Good Results Satisfactory gluing properties Mortising Fair to Good Results Moulding Fair to Good Results Very Good to Excellent Results Fairly Easy to Very Easy Movement in Service Very stable after seasoning Seasoned timber is dimensionally stable, and holds its shape well after manufacture Planing Fairly Easy to Very Easy Fair to Good Results Very Good to Excellent Results Resistance to Impregnation Resistant sapwood Resistant heartwood Poor response to preservative treatment Response to Hand Tools Responds Readily Routing & Recessing Fair to Good Results Fairly Easy to Very Easy Sanding Fairly Easy to Very Easy Turning Fair to Good Results Fairly Easy to Very Easy Painting Very Good to Excellent Results Fair to Good Results Polishing Fairly Easy to Very Easy Polishes and finishes very well Numerical Data Item Green Dry English Bending Strength 7833 11760 psi Crushing Strength 529 926 psi Density 33 lbs/ft3 Hardness 608 lbs Maximum Crushing Strength 3165 6120 psi Shearing Strength 1102 psi Static Bending 4711 7666 psi Stiffness 1029 1509 1000 psi Toughness 221 inch-lbs Specific Gravity 0.4 0.44 Radial Shrinkage 4 % Tangential Shrinkage 7 % Item Green Dry Metric Bending Strength 550 826 kg/cm2 Crushing Strength 37 65 kg/cm2 Density 528 kg/m3 Hardness 275 kg Maximum Crushing Strength 222 430 kg/cm2 Shearing Strength 77 kg/cm2 Static Bending 331 538 kg/cm2 Stiffness 72 106 1000 kg/cm2 Toughness 254 cm-kg Specific Gravity 0.4 0.44 Radial Shrinkage 4 % References Chudnoff, M.,1984,Tropical Timbers of the World,U.S.A.
