Description
The heartwood is pale yellow with white streaks, and indistinctly demarcated from the 10–20 cm wide sapwood. The grain is straight or slightly interlocked, texture medium to fairly coarse. Quartersawn surfaces have an attractive figure. The wood is oily to the touch and fresh wood has an unpleasant smell.
Density
(H=12%) : 0,68
Treatability
Poorly permeable. The heartwood is extremely resistant to impregnation with preservatives, the sapwood is permeable.
Seasoning
Air dries slowly, with a tendency for surface checking, distortion and development of shakes or collapse
Stability
moderately stable
Durability
The wood is not durable, being susceptible to attacks by fungi, dry wood borers and termites
Workability
The wood saws well, with moderate blunting effects on sawteeth. It works well with machine tools, but more difficultly with hand tools. A cutting angle of 20° is recommended in planing. It finishes with difficulty, and a filler is needed. Staining and polishing are satisfactory. Nailing and screwing properties are good, but quartersawn surfaces may split on nailing. The wood glues well. The peeling and slicing properties are good. Steam-bending properties are moderate.
