Deglupta wood
Deglupta (Eucalyptus deglupta, family Myrtaceae) is a tropical timber from Southeast Asia and Oceania. Dry, its Janka hardness is 470 lbf (2,091 N), and air-dry it weighs about 35–50 lb/ft³ (561–801 kg/m³). The figures are from the USDA Forest Products Laboratory's Tropical Timbers of the World, pp. 633–634.
Other names, by country: Bagras (Philippines), Mindanao gum (Australia), Komo, Kamarere (New Guinea).

Strength
Bending strength is the modulus of rupture (MOR); stiffness is the modulus of elasticity (MOE); crushing strength is compression parallel to the grain. The sheet collects these from published tests: it prints one data set, each at the moisture content printed beside it, never restated as 12%.
| Moisture | Bending strength (MOR) | Stiffness (MOE) | Crushing strength |
|---|---|---|---|
| 12% MC | 10,550 psi (73 MPa) | 1.53 million psi (10.5 GPa) | 5,650 psi (39 MPa) |
A dash means the sheet prints no value; none is filled in.
What the data sheet says
- Color, grain and texture
- Heartwood varies from light red, light brown, to dark red-brown; sapwood whitish, not always distinctly marked off from the sapwood. Texture moderately coarse; grain decidedly interlocked, showing a typical ribbon grain when quartered; lustrous; without distinctive odor or taste.
- Working properties
- Both forestand plantation-grown wood easy to saw and machine but does not dress smoothly on quartered faces; takes a good finish.
- Durability
- Heartwood not resistant to attack by decay fungi; sapwood susceptible to powder-post beetle attack.
- Uses
- Furniture components, general construction, millwork, posts and poles (treated), pulp and paper products.
- Where it grows
- Native to the Philippines and other western Pacific islands. Favored as a plantation species throughout the world in lowland humid tropics.
