Heartwood Color Green/grey White Red Brown Occasional dark streaks Golden brown or various shades of brown Darkens after exposure Sapwood Color Red White Wide Light grayish brown Clearly demarcated from heartwood in old trees Grain Even Straight Interlocked Straight to shallowly interlocked Flat-Sawn timber shows the attractive figure to the best advantage. Texture Medium Greasy feel Even textured Luster Low Dull Natural Durability Perishable Susceptible to insect attack Non-resistant to termites Non-resistant to marine borers Non-durable Very low natural resistance to decay in ground contact in the tropical regions Susceptible to termite attack Susceptible to attack by powder-post beetle Odor Spicy odor which persists even after the wood is seasoned Kiln Schedules T8-B3 (4/4) T5-B1 (8/4) US Schedule G (4/4) United Kingdom Drying Defects Distortion May distort and end-split slightly during drying Ease of Drying Moderately Difficult to Difficult Fairly Easy Rapidly Seasons with little degrade Good drying characteristics Kiln Drying Rate Naturally dries quickly Tree Size Bole length is 20-30 m Bole length is 10-20 m Tree height is 30-40 m Tree height is 40-50 m The unbuttressed trees are reported to produce straight and cylindrical boles Product Sources Various species in the genus are reported to produce the timber known commercially as Sepetir. Comments Material loss during conversion is rather high because of the wide and unusable sapwood Oily Waste Factor Blunting Effect Severe dulling effect on cutting edges Cutting Resistance Difficult to saw Movement in Service Small moverment after manufacture Good dimensional stability and shows little movement in use Nailing Fairly Easy to Very Easy Very Good to Excellent Results Fair to Good Results Tends to split during nailing Pre-boring recommended Planing Woodworking properties usually vary Difficult to work in planing, turning, boring, another machining operations Cutting edges should be kept clean and sharp Clean, finished surfaces Can be planed to a smooth finish Material from swampy locations are somewhat harder and heavier Resistance to Impregnation Satisfactory preservative absorption and retention Difficult to treat with presevatives Response to Hand Tools Easy to Work The operation requires sharp cutting edges for best results Sanding Fair sanding qualities Veneering Qualities Best figure display in veneers is achieved through rotary-cutting Steam Bending Poor to Very Poor Results Polishing Fair to Good Results Very Good to Excellent Results Polishing properties improve considerably after surface treatment Staining Fair to Good Results Very Good to Excellent Results Strength Properties Weight=High Resists wearing and marring Hardness = medium Density=High Compression strength (parallel to grain) = high Bending strength in the air-dry condition (about 12%moisture content)is high-comparable to Teak Numerical Data Item Green Dry English Bending Strength 9654 14187 psi Density 46 lbs/ft3 Hardness 1529 lbs Maximum Crushing Strength 4861 7669 psi Shearing Strength 1767 psi Stiffness 1603 1908 1000 psi Weight 41 34. lbs/ft3 Item Green Dry Metric Bending Strength 678 997 kg/cm2 Density 737 kg/m3 Hardness 693 kg Maximum Crushing Strength 341 539 kg/cm2 Shearing Strength 124 kg/cm2 Stiffness 112 134 1000 kg/cm2 References Desch, H.
