The heartwood is yellowish-brown to brown with a dark striping or reddish glints; it is clearly demarcated from the 5 - 8cm wide band of dull gray sapwood. The texture is fine, the grain straight or interlocked. The wood is moderately heavy; moderately hard to hard; elastic; moderately durable, being moderately resistant to fungi and termites and resistant to dry wood borers. It seasons slowly, with only a slight risk of checking or distortion; once dry it is moderately stable in service. The wood has a fairly high blunting effect - stellite-tipped and tungsten carbide tools are recommended; the interlocked grain presents some problems when planing; nailing and screwing are good, but require pre-boring; gluing is correct for internal purposes only. The wood has a range of uses including for high class furniture, cabinet making, turnery, interior joinery and panelling, heavy carpentry, flooring, stairs and veneer[
