Heartwood Color Red Brown Yellow Purple Pink Orange Pink grey Brown Sapwood Color Yellow Somewhat differentiated from the heartwood Pinkish Pale brown Greyish Grain Even Interlocked Figure Straight Rays (figure) Straight Rays figure Interlocked Radial surface usually have numerous and distinct small rays. Texture Medium Fine Coarse Fine Luster Medium High Lustrous Natural Durability Durable Resistant to termites Vulnerable to attack by pin-hole borers, sap-stain fungi and termites Slightly resistant to decay causing organisms Protection of logs with chemicals soon after felling is recommended Odor No specific smell or taste Kiln Schedules The above kiln schedule has been recommended for 4/4 to 6/4 Drying Defects Splitting Moderate end spitting Quartersawn and backsawn material kiln dries at varying rates. Material from Irian Jaya is prone to checking and warping Ease of Drying Moderately Difficult to Difficult Little degrade if dried properly Kiln dries quickly with little degrade Good kiln-drying properties Tree Size Tree height is 20-30 m Tree height is 0-10 m Tree height is 10-20 m Bole length is less than 10 m Trunk diameter is 100-150 cm Trunk diameter is 150-200 cm Substitutes Pau amarello (Euxylophora paraensis ) and Hickory (Carya spp. ). Hickory is similar in strength. Comments Abnormal Wood Tissue - The material is reported to frequently contain reaction wood which can interfere with some machining operations. Reaction wood may be present Cutting Resistance Fairly Difficult to Very Difficult to saw Cutting Resistance with green wood is difficult Cutting Resistance with dry wood is moderate Gluing Fairly Easy to Very Easy Glues well Movement in Service Fair to Good Stability - Medium Movement Excellent Stability - Small Movement Planing Fairly Easy to Very Easy Very Good to Excellent Results Fairly Difficult to Very Difficult Fair to Good Results Planes well, to a good finish Tension wood can produce woolly surfaces Resistance to Impregnation Resistant heartwood Resistant sapwood Sapwood is treatable Heartwood is moderately resistant Response to Hand Tools Easy to Work Sanding Difficult to sand (expect < 50 out of 100 good to excellent results) Woolly nature makes sanding difficult. Surface has tendency to remain fiberous. Turning Fairly Easy to Very Easy Very Good to Excellent Results Fair to Good Results Polishing Very Good to Excellent Results Fair to Good Results Difficult to polish Difficult to finish Woolly nature makes it difficult to finish smoothly Strength Properties Weight = light Surfaces may dent or scratch easily Surfaces may dent easily Compression strength (parallel to grain) = low Bending strength (MOR) = medium Species has medium bending strength in the air-dry condition (about 12 percent moisture content). It is closer in strength to Mahogany than either Teak or White oak, which have higher bending strength. Maximum crushing strength, or compression strength parallel to grain, is low. It is weaker than Mahogany or Teak. It is not hard and can be dented and marred easily. Weight is low. The density is average, or medium.
