Sycamore, Satin

Home » Wood Species » Sycamore, Satin

Satin sycamore is a medium-sized hardwood occurring in coastal rainforest areas of northern Queensland, Indonesia (Irian Jaya) and Papua New Guinea.

The heartwood of this species is a pale or pinkish-brown colour, not visually distinct from the sapwood. The texture of satin sycamore timber is fine and even. Its grain is usually straight, with occasional interlocking.

Common applications of satin sycamore furniture, joinery and as a decorative veneer. It is sometimes used for sides and backs (but not generally soundboards) of acoustic guitars.

Satin sycamore glues relatively well, but the dry wood rapidly dulls cutting edges.

Satin sycamore is classed as 'vulnerable' in the IUCN Red List of Threatened Species. Commercial availability of satin sycamore timber products is currently limited to Queensland.
