Other Uses

The heartwood is dull brown to dark purplish brown, slightly darkening upon exposure; it is distinctly demarcated from the 4 - 8cm wide band of greyish white to pale brown sapwood. The grain is straight to slightly interlocked; the texture coarse and even. The wood is moderately heavy; soft to moderately hard; it is moderately durable, being susceptible to powder-post beetle, pinhole borer and marine borer attacks, moderately resistant to termites and fungi, and resistant to dry wood borers. It seasons somewhat slowly with a high risk of distortion; once dry it is stable in service. The wood saws fairly easily although it requires some power, and it works easily with both hand and machine tools. It usually contains silica (up to 0.5%) and has moderate blunting effects on cutting edges; stellite-tipped saw teeth and tungsten-carbide cutting edges are recommended. In planing and moulding operations a 15 - 20° cutting angle is recommended, especially when interlocked grain is present. It can be finished to a nice surface, but the use of a filler may be required. The wood is not liable to splitting on nailing and screwing, and has good holding properties. The gluing, staining and polishing properties are good when a filler is used. The wood is suitable for the production of sliced veneer. The wood is used for construction, exterior and interior joinery, boat building, furniture, cabinet work, high class furniture, veneer and plywood. It is suitable for flooring, interior trim, vehicle bodies, toys, novelties, boxes, crates and turnery[
