The heartwood is red-brown, grey or red with dark streaks and is
moderately clearly demarcated from the up to 8 cm wide, whitish
sapwood with a pink or brown tinge. The grain is interlocked,
texture medium to coarse. The wood is lustrous and contains a
yellow or brown oleoresin.
The wood is lightweight to medium-weight, with a density of 510–680
kg/m³ at 12% moisture content, moderately soft but tough and
strong. The shrinkage rates of the wood are moderate, from green to
oven dry are 2.8–3.5(–5.6)% radial and 3.7–7.0(–9.3)% tangential.
Air drying is fairly fast with little degrade. Once dry, the wood
is moderately stable in service. At 12% moisture content, the
modulus of rupture is 56–114 N/mm², modulus of elasticity 6280–9700
N/mm², compression parallel to grain 25–63 N/mm², shear 5–15 N/mm²,
cleavage 12–28 N/mm and Chalais-Meudon side hardness
The wood is easy to saw and work with both hand and machine tools,
with little blunting effect on saw teeth and cutting edges. The
wood stains satisfactorily but needs a filler before polishing. In
general it nails and screws well and glues correctly. It can be
readily peeled into veneer, but the veneer may warp during drying.
The wood is not durable, being susceptible to attacks by fungi,
termites, pinhole borers, Lyctusand
marine borers. The heartwood is resistant to impregnation with
preservatives and the sapwood has a variable permeability.
