attractive appearance. The sapwood is pale in colour and sharply demarcated from heartwood;
sapwood and heartwood are often used in furniture to give two toned effect. The grain is straight
sometimes irregular and texture fine. The bole is 18-21m in length with a diameter of 40-75cm.
Physical and Mechanical Properties
A very hard, very heavy wood with medium movement. Excellent mechanical strength:
Air dried density (12%) - 1060kg/m3
Bending strength (at 12%) - 213 N/mm2
Modulus of elasticity (at 12%) - 23630 N/mm2
Crushing strength (at 12%) - 110N/mm2
Natural Durability
The heartwood is durable and extremely resistant to insects, decay and preservatives but not to
marine borers. The sapwood is permeable.
Timber Processing
Drying - Dries slowly with appreciable surface checking. Kiln Schedule B.
Working - Difficult to work owing to hardness and interlocked grain. Easy to scrape and sand and
gives a fine finish. There is a tendency for end splitting but distortion is not serious. Blunting effect
is moderate to high. Suitable for bends of moderate radius of curvature if well supported with a
metal strap.
Assembly - Difficult to nail and screw and tends to split, but fastenings are held well. Pre-boring is
necessary.
Finishing - Finishes smoothly and polishes well. Stains will not penetrate the timber.
Uses

flooring and panelling. Very suitable for inlay work and turnery.
