TATABU<br />
Scientific name: Diplotropis purpurea<br />
Family: Papilionaceae<br />
Standard name: Sucupira<br />
Other names: Sucupira, Alcoruoque, Zwarte Kabbes<br />
Wood Appearance<br />
The heartwood is dark chocolate-brown in colour with conspicuous paler markings, giving a<br />
decorative appearance which may be enhanced on quartered surface by a stripe figure. The sapwood<br />
is whitish, sharply demarcated from the heartwood. Grain is interlocked, sometimes irregular and<br />
the texture is moderately coarse. The bole is 18-<strong>21</strong>m in length and diameter 40-60(-100) cm.<br />
Physical and Mechanical Properties<br />
A heavy, strong, durable wood possessing high strength properties. Medium shrinkage, relatively<br />
stable once dry.<br />
• Air dried density (12%) - 910kg/m 3<br />
• Bending strength (at 12%) - 156 N/mm 2<br />
• Modulus of elasticity (at 12%) - 18000 N/mm 2<br />
• Crushing strength (at 12%) - 88 N/mm 2<br />
Natural Durability<br />
Very resistant to decay even under exacting conditions of use. Highly resistant to fungi and termite<br />
attacks.<br />
Timber Processing<br />
Drying - Dries readily but slowly, without distortion or checking.<br />
Working - Difficult to work due of its high density and interlocked and irregular grain, but can be<br />
finished to a smooth surface. Turns well.<br />
Assembly - Glues well and holds nails and screws hold well.<br />
Finishing - Polishes satisfactorily after filling.<br />
Uses<br />
Has a decorative appearance and is of interest for turned work and as a veneer for inlays in high<br />
grade furniture. Suitable for exterior and interior joinery, turnery, paneling and tool handles. A very<br />
useful timber with many applications.<br />
Supplies<br />
Occurs widely but not abundantly in the <strong>Guyana</strong> forests. Regular supplies in modest quantities are<br />
available.<br />
