Rays show up as pink bands or spots, according to cut. Sapwood Color White Yellow Color not distinct from heartwood Grain Figure Distinct (figure) Even Closed Wavy Straight Rays (figure) Weak (figure) Distinct figure Wavy Weak figure Straight Rays figure Even Rays produce a conspicuous figure on quartersawn surfaces Texture Medium Coarse Fine Medium Luster Low Natural Durability Moderately durable Non durable Susceptible to attack from powder post (Lyctid & Bostrychid) beetles Susceptible to marine borer attack Susceptible to termite attack Susceptible to marine borer attack Susceptible to attack from termites (Isoptera) Perishable Moderately durable Odor No specific smell or taste Light-Induced Color Change Darker Kiln Schedules Kiln Drying Rate (in days) is rather slow UK=C US=T3C2/T3C1 Fr=3 Dry at a slow speed Drying Defects Moderate end spitting Moderate cupping Moderate surface checking Moderate collapse and honeycombing Timber is liable to split and cup during drying, particularly backsawn boards Ease of Drying Fairly Easy Moderate The wood is generally moderately difficult to dry, especially backsawn material Kiln Drying Rate Slow (18-28 days for boards < 32 mm, to 52-84 days for boards >= 63 mm) Tree Size Tree height is 0-10 m Tree height is 10-20 m Tree height is 40-50 m Boles that are often straight and clear of branches to 20 feet (6 m). T Comments General finishing qualities are rated as satisfactory Cutting Resistance Cutting Resistance with dry wood is easy Saws without difficulty Cutting Resistance with green wood is easy Quartersawing is reported to emphasize grain pattern and also facilitates seasoning. Gluing Easy to glue Satisfactory gluing properties Nailing Possible if prebored Moderate nailing properties Planing Easy to plane Planes well, to a good finish The timber is generally easy to plane, mould, bore, and mortise, but it requires sanding after most machining operations in order to obtain a smooth surface. Resistance to Impregnation Heartwood is moderately resistant Response to Hand Tools Easy to Work Easy to machine Good Sanding Good characteristics Screwing Moderate screwing characteristics Turning Fairly Easy to Very Easy Turns with moderate ease Finish is generally satisfactory Easy to turn Polishing Satisfactory results Good results Varnishing Good results Strength Properties Density (dry weight) = 46-52 lbs/cu. ft. Bending strength (MOR) = medium Shrinkage, Tangential = large Shearing strength (parallel to grain) = medium Shrinkage, Radial = fairly large Max. crushing strength = medium Hardness (side grain) = medium Shrinkage, Tangential = moderate Shrinkage, Tangential = fairly large Shrinkage, Radial = very small Shrinkage, Radial = small Shrinkage, Radial = moderate Shrinkage, Radial = large Modulus of Elasticity (stiffness) = medium Modulus of Elasticity (stiffness) = high Max. crushing strength = high Shrinkage, Tangential = small High in density Hardness = medium Compression strength (parallel to grain) = high Bending strength (MOR) = very high Air-Dried condition about 12% moisture content It resists denting and marring about as well as white oak or birch Much stronger than Teak in the air-dry condition Other species high in compression strength include Teak, White oak, and Hard maple.
