Heartwood Color Brown Red Pink Yellow to golden-yellow to orange Brown Sapwood Color Green/Grey White Paler than heartwood Sapwood is considered narrow Grain Interlocked Straight Even Interlocked Generally straight, but not always Texture Medium Fine to medium Medium Fine Greasy feel Luster High Lustrous Natural Durability Perishable Non-durable Very durable Very durable Resistant to attack from powder post (Lyctid & Bostrychid) beetles Resistant to attack from termites (Isoptera) Pinworms (ambrosia beetles) may be present in the felled log Good weathering properties Durable Durable Heartwood is resistant to termites but logs are vulnerable to attack by pinhole borers. The material has good weathering properties. Odor Has an odor No specific smell or taste Kiln Schedules Dry at a slow speed Drying Defects Distortion Collapse Moderate surface checking Ease of Drying Fairly Easy Medium to High Shrinkage Radial and tangential shrinkage from 1-2% Moderate Tree Identification Bole/stem form is misshapen Bole/stem form is buttressed Tree Size Tree height is 30-40 m Blunting Effect Blunting effect on machining is fairly severe Blunting effect on machining is moderate Boring Fair to good results Fairly easy to very easy Easy Surfaces of straight-grained material are generally clean if cutters are kept very sharp. Carving Fair to Good Results Fairly Easy to Very Easy Arving qualities are generally good, especially in straight-grained material. Cutting Resistance Easy to saw Reported to be hard and dense Described as heavy Cutting Resistance with dry wood is difficult Gluing Fair to Good Results Moderate gluing properties Fairly difficult to glue Mortising Fair to Good Results Fairly Easy to Very Easy Straight-Grain wood responds best Moulding Fair to Good Results Fairly Easy to Very Easy Yields clean surfaces Timber is reported as hard and heavy Requires very sharp cutting edges Nailing Fair to Good Results Fairly Easy to Very Easy Holds nails well Planing Fairly Easy to Very Easy Fair to Good Results The timber is hard and heavy, but it is reported to plane to yield relatively clean surfaces, except when interlocked grain is present. Resistance to Impregnation Heartwood is extremely resistant Resistance to Splitting Poor Response to Hand Tools Responds Readily Easy to Work Moderate working qualities Utting edges may dull rather rapidly since the wood is hard and heavy. Routing & Recessing Fairly Easy to Very Easy Material with interlocked grain requires sharp cutting edges Hard and heavy wood Good in both routing and recessing. Sanding Fair to Good Results Contains alkaloids giving it good acid resistance Green wood sands rather well Turning Fair to Good Results Very Good to Excellent Results Yields clean surfaces Requires sharp cutters Easy to turn Polishing Fair to Good Results The wood has good polishing properties. Strength Properties Max. crushing strength = high Bending strength (MOR) = high Shearing strength (parallel to grain) = high Density (dry weight) = 61< Shrinkage, Tangential = very small Shrinkage, Radial = very small Shrinkage, Tangential = small Density (dry weight) = 53-60 Bending strength (MOR) = medium Numerical Data Item Green Dry English Bending Strength 14328 19771 psi Crushing Strength 2122 2445 psi Density 61 lbs/ft3 Hardness 2032 lbs Maximum Crushing Strength 7755 10244 psi Shearing Strength 2670 psi Static Bending 9477 10702 psi Stiffness 2120 2432 1000 psi Toughness 132 inch-lbs Weight 60 49 lbs/ft3 Radial Shrinkage 2 % Tangential Shrinkage 4 % Item Green Dry Metric Bending Strength 1007 1390 kg/cm2 Crushing Strength 149 171 kg/cm2 Density 977 kg/m3 Hardness 921 kg Maximum Crushing Strength 545 720 kg/cm2 Shearing Strength 187 kg/cm2 Static Bending 666 752 kg/cm2 Stiffness 149 170 1000 kg/cm2 Toughness 152 cm-kg Weight 961 785 kg/m3 Radial Shrinkage 2 % References Alston, A.S.,1966,Natural Heartwood Durability,Fiji Forestry Department, Suva.
