The sapwood is easier to pulp. [19] due to a more open structure and less content of extractive than the heartwood. The fibre length of sapwood is generally longer than the fibre length of heartwood. The sapwood is also normally lighter and that is an advantage when producing mechanical pulp as less bleaching of wood pulp is needed.
The heartwood is golden to dark brown; the sapwood is white to pale brownish white. The heartwood is durable (its specific gravity is 0.7 – 0.8) and is very resistant to fungi, but the sapwood is readily attacked by dry-wood termites and borers.

It is brownish-purple with many fine darker stripes and occasional irregular swirls. Occasionally it contains pale streaks of a similar colour to the sapwood, as in the picture.

Inside, the living sapwood is pale pink or whitish in colour, while the inner heartwood is dark red-brown to chocolate brown, with conspicuous white deposits of silica.
