Data source is World Conservation Monitoring Center Classified as vulnerable in the Philippines Distribution Overview The ball nut is a native tree of coastal areas of northern Australia. It prefers the relatively sheltered, well-drained sites on sandy beaches and dune systems along the coastline of central and northern Queensland. Although it will persist on the drier parts of the coastline, it grows more vigorously and exhibits greater tolerance to exposure on the higher rainfall areas of the tropical coast. Native to coasts of the Indian and Pacific Oceans, introduced to some places such as Hawaii. Common in Singapore. Heartwood Color Yellow Orange Brown Red Reddish brown Color changes with age The color of the heartwood is described as reddish-brown, with darker streaks on longitudinal surfaces. The color is reported to turn dull gray with age. Various woods of Calophyllum are very difficult to differentiate Sapwood Color White Yellow Red Pinkish-brown Pale straw Clearly differentiated from the heartwood Grain Interlocked Moderately to severely interlocked Texture Fine Medium Luster Medium Low Lustrous Natural Durability Durable Perishable Moderately durable Non-durable Susceptible to attack by marine borers and termites Heartwood seldomly attacked by borers, but is is susceptible to attack by termites and marine borers such as shipworms (Teredo spp.) and gribble (Limnoria spp.) Odor No specific smell or taste Kiln Schedules T2 - D4 (4/4); T2 - D3 (8/4) US Schedule A (4/4) United Kingdom. Drying Defects Checking Slight surface checking Moderate twist/warp Moderate end spitting Ease of Drying Special attention required Fair Weight down stacks to minimize warping Tree Size Bark width is 10-15 mm Tree height is 20-30 m Tree height is 10-20 m Bark width is 15-20 mm Bole is often crooked and leans at an angle of less than 45 degrees to the ground. Comments Deposits in Wood - Wood vessels contain a red deposit. Ornamental species The species is highly favored as an ornamental tree. It is also widely cultivated for its oil in many tropical regions. Cutting Resistance Material with interlocked grain can be difficult. Sawn surfaces can be wooly Mortising Interlocked grain effects mortising Difficult to mortise Moulding Requires very sharp cutting edges Very sharp edges required to keep grain from tearing Movement in Service Excellent Stability - Small Movement Medium Moderate dimensional stability can be attained after seasoning. Medium movement can occur after manufacturing. Planing Special attention required Poor planing characteristics Interlocked grain makes planing difficult. Recommended that sharp cutting edge and reduced cutting angle are used Resistance to Impregnation Resistant heartwood Resistant sapwood Sapwood is easily treatable Heartwood is moderately resistant Response to Hand Tools Fairly Difficult to Difficult to Work Easy to Work Wood usually has interlocked grain, making it more difficult to work with hand tools Special attention required For best results cutting edges should be kept sharp. Interlocked grain commonly causes tearing Polishing Requires a filler High polish Strength Properties Compression strength (parallel to grain) = high Bending strength in the air-dry condition (about 12 percent moisture content) is high - comparable to Teak. Maximum crushing strength, or compression strength parallel to grain, is high. Some familiar species with high crushing strength parallel to grain include Hard maple, Teak, and White oak. It is fairly hard, resisting wear, denting, and marring fairly well. It is heavy.
