Other Uses

Furniture  Wood

Other Uses: The heartwood is a deep, dark brown with lighter, thin streaks; it is clearly demarcated from the 3 - 8cm wide band of light yellow sapwood. The texture is medium; the grain straight or slightly interlocked. The wood is very heavy; very hard; very strong; very elastic; very durable, being very resistant to fungi, dry wood borers and termites. It seasons slowly, with a high risk of checking but only a slight risk of distortion; once dry it is poorly to moderately stable in service. It is a very hard wood and has a fairly high blunting effect - stellite-tipped and tungsten carbide tools are recommended; nailing and screwing are good, but require pre-boring; gluing is poor. A high quality, very strong, durable and attractive timber, its use is limited mainly by the small size of heartwood obtained from the logs. It is used for purposes such as high class furniture, cabinet making, musical instruments of various types, turnery, sculpture, flooring, panelling, wooded goods, items such as arches that require forming; veneer etc[848 ].
