Black Bean 

Castanospermum australe


A large hardwood that grows from northern NSW to northern QLD. The heartwood is a very dark brown with lighter streaks. This timber is a little greasy to the touch. The grain is often wavy or interlocked.


Works well but the dust is shocking and can cause a severe reaction. Difficult to glue due to the oil in the timber.


Excellent cabinet timber. Was once used as boards for electrical installations due to very low conductivity.


Extremely limited.


Janka 7.5 770kg/m3.


Reasonably durable.
