Although we have no more specific information about the wood of this species, the following description is for the timber group to which this species belongs:-
The heartwood is yellow-brown to chocolate reddish-brown, with an occasional dark striping; it is not clearly demarcated from the 5 - 7cm wide band of light yellow-brown sapwood. The texture is fine to medium; the grain straight or interlocked; lustre is rather low; without distinctive odour or taste. The wood is moderately heavy; moderately hard; moderately durable, being resistant to dry wood borers, moderately resistant to fungi but susceptible to termites. It seasons slowly, with a high risk of checking and distortion; once dry it is moderately stable in service. It can be worked with ordinary tools; it is moderately easy to resaw and cross-cut; planing is fairly easy and the surface produced is smooth; the wood tends to split when nailing or screwing and nail holding is poor; gluing is correct; there is some resistance to acids. The wood has a wide range of applications, for purposes such as light construction, door and window frames, carpentry, flooring, joinery, turnery and veneer[
