The heartwood is a pinkish brown to red brown, sometimes olive brown; it is clearly demarcated from the 3 - 6cm wide band of sapwood. The texture is medium; the grain straight or interlocked, sometimes wavy; the unseasoned wood has an unpleasant odour. The wood is moderately heavy; moderately hard; moderately durable, having a good resistance to dry wood borers, moderate resistance to fungi, but poor resistance to termites. It seasons at a normal rate, with a high risk of checking and distortion; once dry it is poorly stable in service. It has moderately good working properties; saws and planes well; nailing and screwing are good; gluing is correct; it requires care in polishing. However, it dulls saws and cutting edges rather quickly because of the accumulation of silica in the parenchyma and ray cells - stellite-tipped and tungsten carbide tools are recommended. Chipped or torn grain is likely to occur when roey grain is present, and fuzzy surfaces and tearing are apt to occur in boring. The wood is used locally for such purposes as joinery, flooring, interior trim, furniture, and millwork. It has been used in the superstructures of bridges and has also been found suitable for packing cases, outside and inside sheathing, rafters, and implements[
