Wood Technology Transfer Fact Sheet
Other Common Names: Tamaga (Burma), Bois rouge (New Caledonia), Chinaberry tree (United States).
Distribution: Native to the Himalayan region and perhaps elsewhere in Asia. Cultivated throughout the tropical and subtropical regions of the world as an ornamental.
The Tree: Open-grown trees with straight, fairly cylindrical boles to a length of 12 ft; trunk diameters 1 to 2 ft. Bark, leaves, and fruit have some medicinal applications.
General Characteristics: Heartwood reddish, darkening on exposure to a reddish brown marked with dark striations caused by zones of earlywood pores; sapwood yellowish white, distinct. Grain straight; texture coarse and uneven; lustrous; without characteristic odor or taste.
Weight: Basic specific gravity (ovendry weight/green volume) 0.47; air-dry density 36 pcf.
Mechanical Properties: (First set of data based on the 2-cm standard, the second set on the 2-in. standard.)
Moisture content Bending strength Modulus of elasticity Maximum crushing strength
(%) (Psi) (1,000 psi) (Psi)
12% (52) 16,000 1,300 8,100
Green (27) 8,500 1,150 3,920
Amsler toughness 327 in.-lb for dry material (2-cm specimen).
Drying and Shrinkage: The timber seasons exceptionally well with little or no degrade due to warping or checking. No data available on kiln schedules. Shrinkage green to ovendry: radial 5.0%; tangential 8.5%; volumetric 13.5%.
Working Properties: Easy to saw and machine, and peels well on a veneer lathe; dresses to a smooth finish and takes a good polish.
Durability: The timber is reported to be resistant to attack by decay fungi and termites.
Preservation: No information available.
Uses: Turnery, furniture components, decorative veneers, novelty items, boxes and chests.
