Uses: Greenheart timber is suitable for all marine construction work including ship construction. Greenheart wood can also be used for bridges, heavy duty flooring, chemical vats, billiard cue butts, turnery, fishing rods, longbows, and more.
General Description: The evergreen Greenheart tree varies considerably in colour, from yellow-green, golden yellow, light olive, dark olive, yellow-brown, dark brown to black. Decayed or defective greenheart logs have a yellow colour. Greenheart wood grain is straight to interlocked or roey and the texture fine and even, lustrous and cold to the touch.
Weight 1030 kg/m³ (64 lb/ft³); specific gravity 1.03.
Greenheart timber has an exceptionally heavy density, and very high bending and crushing strengths; it has a very high stiffness and a high resistance to shock loads. The wood has a moderate steam bending classification although requires extra efficient support on the outer face.
Greeenheart wood dries very slowly with considerable degrade with checking and end splitting. Boards over 1” (25mm) thickness should be partly air dried before kilning and existing shakes are liable to extend and splitting of knots may occur. Medium movement in service.
Greenheart timber is very durable. It has excellent resistance to marine borers and although Greenheart sapwood is liable to attack by pinhole borers, the heartwood is immune. It is extremely resistant to preservative treatment.
