Wood Technical Fact Sheet
Other Common Names: Jarul (India), Banglang (Vietnam), Intanin (Thailand), Bungor (Malaya, Sabah), Banaba (Philippines), Bang-lang (Cambobia).
Distribution: Indo-Malayan region including Indochina and extending into Indonesia and the Philippines; along rivers and on moist flat land; often cultivated as an ornamental.
The Tree: Reaches a height of 100 ft with trunk diameters of 3 to 4 ft on favorable sites; boles to 40 ft in length, often fluted.
General Characteristics: Heartwood light red to reddish brown, darkening on exposure; sapwood light yellow brown to grayish white, rather wide. Grain usually straight; texture moderately fine to rather coarse; rather lustrous; without distinctive odor or taste. Wavy grain, if present, and semiring porous growth produce an attractive figure.
Weight: Basic specific gravity (ovendry weight/green volume) 0.55; air-dry density 43 pcf.
Mechanical Properties: (First two sets of data based on the 2-in. standard; third set on the 2-cm standard.)

Janka side hardness about 1,055 lb for dry material. Amsler toughness 250 in.-lb at 12% moisture content (2-cm specimen).
Drying and Shrinkage: Reported to be easy to season with little or no degrade due to warping and checking. No data available on kiln schedules. Shrinkage green to ovendry: radial 4.4%; tangential 6.8%; volumetric 12.7%.
Working Properties: The timber saws and works well, finishes to a smooth surface, and takes a good polish.
Durability: Generally classified as moderately durable and somewhat resistant to termites. Sapwood liable to powder-post beetle attack.
Preservation: Heartwood reported to be very difficult to treat with absorptions of preservative oils less than 2 pcf using a pressure-vacuum system.
Uses: Furniture, interior joinery, boatbuilding, general construction, parquet flooring, paneling.
