Heartwood Color Yellow Orange Green/grey Reddish brown Red Pinkish brown Sapwood Color Yellow White to yellow Light reddish yellow Color not distinct from heartwood Grain Even Straight Interlocked Occasionally interlocked, but not always Generally straight, but not always Texture Medium Fine Uneven Medium to coarse Luster Medium Non-lustrous Natural Durability Susceptible to insect attack Perishable Non-durable Moderately durable Non-resistant to powder post beetles Non-resistant to termites Non-resistant to marine borers Very little natural resistance Susceptible to termite attack Sapwood susceptible to attack by powder post beetles Logs are susceptible to attack by pinhole borer and longhorn beetle. Odor No characteristic taste May have a slightly disagreeable smell when green Silica Content Some species in the genus are siliceous Drying Defects There is a tendency for thin material to cup during air-drying. Close vertical stickers and weighting down stacks can eliminate or reduce cupping Ease of Drying Rapidly Good drying characteristics Dries at a fairly rapid rate Neesia timbers are reported to shrink slightly less than that of Durio Kiln Drying Rate Naturally dries quickly Tree Size Tree height is 20-30 m Tree height is 10-20 m Tree height is 30-40 m Bole length is 0-10 m Bole length is 20-30 m Bole length is 10-20 m Tree height is 0-10 m Bark width is 15-20 mm Bark width is 10-15 mm Bark width is 25-30 mm Can reach 54 m. in height Cutting Resistance Easy to saw Low resistance Gluing Fairly Easy to Very Easy Very good properties Nailing Fairly Easy to Very Easy Easy to nail Planing Very Good to Excellent Results Fair to Good Results Planes to a smooth surface Wood produced by Neesia trees tends to pick up on quartersawn surfaces Resistance to Impregnation Easily treated by pressure impregnation and open-tank processes Can be treated by cold soaking using preservative oils. Response to Hand Tools Easy to Work Turning Responds well Polishing Very Good to Excellent Results Fair to Good Results Requires a filler Fair results Strength Properties Surfaces may dent or scratch easily Max. crushing strength = low High in density Heavy Compression strength (parallel to grain) = low Bending strength (MOR) = medium Numerical Data Item Green Dry English Bending Strength 7511 9853 psi Crushing Strength 394 488 psi Density 39 lbs/ft3 Hardness 666 lbs Maximum Crushing Strength 3837 5094 psi Shearing Strength 1057 psi Static Bending 4475 5699 psi Stiffness 1365 1511 1000 psi Work to Maximum Load 6 9 inch-lbs/in3 Specific Gravity 0.49 Weight 38 31. lbs/ft3 Radial Shrinkage 4 % Tangential Shrinkage 7 % Volumetric Shrinkage 12 % Item Green Dry Metric Bending Strength 528 692 kg/cm2 Crushing Strength 27 34 kg/cm2 Density 624 kg/m3 Hardness 302 kg Maximum Crushing Strength 269 358 kg/cm2 Shearing Strength 74 kg/cm2 Static Bending 314 400 kg/cm2 Stiffness 95 106 1000 kg/cm2 Work to Maximum Load 0.42 0.63 cm-kg/cm3 Specific Gravity 0.49 Weight 608 496. kg/m3 Radial Shrinkage 4 % Tangential Shrinkage 7 % References Chudnoff, M.,1984,Tropical Timbers of the World,U.S.A.
