Blackbean |
Name
Blackbean (Castanospermum australe)
Type
Hardwood.
Other Names
Also known as Moreton Bay bean, Moreton Bay
chestnut, and beantree.
Sources
Grows in Australia, New South Wales, and Queensland.
Appearance
Typically straight grained, sometimes slightly interlocked
with a coarse, uneven texture and a "greasy" feel.
Narrow, chocolate-brown heartwood, often with darker
streaks (turning almost black with age) and yellowish
white sapwood.
Physical Props
Moderately heavy and tough with medium strength, low
stiffness and shock resistance, high decay resistance, and
medium movement in service. Not suitable for steam
bending due to its brittleness.
Working Props
Can be difficult to machine due to minerals in wood.
Turns well. Greasy nature can complicate gluing. Screws
and nails well and polishes to an excellent finish.
Uses
Valued for high-end furniture, cabinetry, interior joinery,
decorative veneer, carving, and turned items such as
brushbacks, tool handles, dowels, and chair parts. Also
suitable for switch boards and electrical fittings due to its
good insulating properties.
