Natural attributes - structure - origins: Extremely heavy wood (1090 kg/m³) with dark brown to black heartwood, with strips of gray-brown, yellow-brown and sallow brown. Straight grain wood, but sometimes with irregular and wavy design. It grows in the Celebes Islands.

Natural durability in time: Very durable wood. The logs are affected by the bug Longhorn beetle. The wood is moderately resistant to termites.

Mechanical attributes: Extremely heavy wood, compact and hard. The black heartwood tends to be fragile and therefore it is used for decorations.

WOOD PROPERTIES AND PROCESSING OPERATIONS

Drying Behavior and stability after drying: Hard to dry. Trees are usually deadened two years before cutting and then left to dry in the air in the form of thick sawns for 6 months. Quick drying should be avoided. There is very small variability in size after drying.

Impregnation behavior: Extremely resistant to impregnation.

Bending behavior: Has good flexural behaviour when steam bending.

Working properties - tool blunting: Hard to process with tools and machinery since it is fragile. Causes a high degree of tool blunting.

Nailing and screwing: Pre-drilling is necessary.

Gluing behavior: Difficult to glue.

Dyeing and finishing: Excellent finish.

APPLICATIONS

Cabinets, tool handles, walking sticks, tobacco boxes, musical instruments, pads, billiard cues, turners, decorative veneer cladding.
