They are very common in areas with seasonal flooding in Sabah, Malaysia. Heartwood Color Yellow Orange White Reddish brown Purplish Light to dark reddish-brown Sapwood Color Yellow White White to yellow Lighter than heartwood Clearly demarcated from heartwood in old trees Grain Even Straight Straight May be interlocked Texture Fine Fine Even textured Natural Durability Non-durable Durable Perishable Moderately durable Susceptible to insect attack Resistant to powder post beetles Resistant to attack from powder post (Lyctid & Bostrychid) beetles Moderately durable Natural resistance to decay is variable Durable Odor No specific smell or taste Kiln Schedules T2-C2(4/4);T2-C1(8/4)US Shrinkage from green to 12% MC Radial:4.5% Tangential:8.0% Drying Defects Distortion Prone to checking, warp and collapse Ease of Drying Fairly Easy Rapidly Very difficult to season Air drying to 25% moisture content prior to kiln drying is suggested Kiln Drying Rate Naturally dries quickly Rapid Drying rate is fairly rapid to fast Tree Size Tree height is 40-50 m Trunk diameter is 150-200 cm Tree height is 20-30 m Tree height is 30-40 m Trunk diameter is 100-150 cm Tree height is 50-60 m Bole length is 10-20 m Bole length is 20-30 m Blunting Effect Slight blunting effect on cutting tools Boring Responds readily to ordinary tools in boring to produce smooth bores Carving Good results Cutting Resistance Low resistance to sawing Fairly easy to saw Mortising Mortises readily to yield clean surfaces Moulding Generally easy moulding operations Movement in Service Unstable with Poor Stability - Large Movement Excellent Stability - Small Movement Moderate dimensional stability after seasoning Medium movement after manufacture Nailing Pre-Drilling recommended in nailing operations Planing Very Good to Excellent Results Fair to Good Results Good planing properties Generally clean planed surfaces Resistance to Impregnation Permeable sapwood Very resistant to impregnation Sapwood is permeable Heartwood is resistant Extremely resistant Response to Hand Tools Easy to Work Responds well to hand tools Routing & Recessing Easy recessing characteristics Sanding Good sanding properties Turning Yields clean surfaces Painting Very Good to Excellent Results Fair to Good Results Polishing Polishes easily Finished easily Strength Properties Density (dry weight) = 38-45 lbs/cu. ft. Density (dry weight) = 46-52 lbs/cu. ft. Shearing strength (parallel to grain) = high Modulus of Elasticity (stiffness) = medium Max. crushing strength = medium Hardness (side grain) = medium Density (dry weight) = 31-37 lbs/cu. ft. Bending strength (MOR) = medium Shrinkage, Tangential = moderate Shrinkage, Tangential = large Shrinkage, Tangential = fairly large Shrinkage, Radial = small Shrinkage, Radial = moderate Shrinkage, Radial = fairly large High in density Hardness = medium Compression strength (parallel to grain) = high Resistant to wearing and marring The bending strength of air-dried wood of the species is similar to that of Teak, which is considered to be strong. Other species in this range include Teak, White oak, and Hard maple (for high compression parallel to grain).
