Heartwood Color Red Brown Purple Pink Yellow to golden-yellow to orange Pale red to pink Color fades with exposure The heartwood has a brilliant rose color initially, but the color is reported to fade to a dull orange after prolonged exposure Sapwood Color White Brown Pink Yellow Yellowish Pinkish Color not distinct from heartwood Sapwood is pale yellowish or pinkish, and is irregular in thickness and outline. It is often not clearly distinguished from the heartwood Grain Interlocked Slightly interlocked Texture Fine Medium Very fine Dense Luster Low Wood surface is glossy Natural Durability Durable Susceptible to insect attack Non-resistant to powder post beetles Moderately durable Non-resistant to marine borers Non-resistant to termites Resistant to insect attack Naturally resistant to decay Durable The timber is naturally resistant to decay, even in contact with the ground, and is rarely attacked by insects Odor No specific smell or taste Drying Defects Internal Honeycombing Possible Collapse Stack properly to prevent warping Slight tendency to check Ease of Drying Moderately Difficult to Difficult Fairly Easy Slowly Stack timber carefully to minimize degrade Special care required to prevent defects Fairly easy Kiln Drying Rate Naturally dries slowly Tree Size Bole length is 10-20 m Tree height is 40-50 m Trunk diameter is 100-150 cm Bole length is 20-30 m Tree height is 30-40 m Trees in the Neonauclea genera are described as often small to medium, with boles that are generally straight but not very long. Trunk diameter of N. calycina is about 32 inches (80 cm) at maturity Comments Several species in the Neonauclea genera are mixed and marketed together under the trade name Calamansanay. With the exception of slight differences in color and texture, the timber of all the species is very similar Blunting Effect Little Gluing Fairly Easy to Very Easy Fair to Good Results Fairly Difficult to Very Difficult Movement in Service Excellent Stability - Small Movement Nailing Fairly Easy to Very Easy Resistance to Impregnation Resistant heartwood Resistant sapwood Permeable sapwood Response to Hand Tools Easy to Work Fairly Difficult to Difficult to Work Difficult to machine Calamansanay timber is rather difficult to work because it is dense, hard, and usually contains interlocked grain.
