Eveuss wood
Eveuss (Klainedoxa gabonensis, family Irvingiaceae) is a tropical timber from Africa. Air-dry, it weighs about 68 lb/ft³ (1,089 kg/m³). The figures are from the USDA Forest Products Laboratory's Tropical Timbers of the World, pp. 443–444.
Other names, by country: Kroma (Ivory Coast), Odudu (Nigeria), Mututtu (Uganda).

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 2 data sets, from different tests and sources, so they can differ widely; all are shown, in the sheet's order, each at the moisture content printed beside it, never restated as 12%.
| Moisture | Bending strength (MOR) | Stiffness (MOE) | Crushing strength |
|---|---|---|---|
| 12% MC | 26,000 psi (179 MPa) | 3.52 million psi (24.3 GPa) | 13,100 psi (90 MPa) |
| 12% MC | 27,400 psi (189 MPa) | 3.08 million psi (21.2 GPa) | 12,600 psi (87 MPa) |
A dash means the sheet prints no value; none is filled in.
What the data sheet says
- Color, grain and texture
- Heartwood orange-yellow or goldenbrown, turning on exposure to a dark brown with black veining; sapwood not clearly demarcated. Texture fine to medium; grain straight to interlocked; without characteristic odor or taste.
- Working properties
- Saws reasonably well; difficult to work with hand tools, but works rather easily with machine tools. Dresses to a smooth finish.
- Durability
- Heartwood highly durable, immune to termite attack.
- Uses
- Heavy durable construction, factory flooring, mine timbers, railroad crossties, tool handles.
- Where it grows
- From Guinea to the Congo Basin, Uganda, and Sudan; occurs in evergreen forests on sandy soil.
