Andiroba
Species profile
The colour of the heartwood is red brown, with a nice golden lustre. It resembles mahogany. Compression failure appears more often. The sapwood is not clearly demarcated. The grain is mainly straight, sometimes irregular or interlocked. The texture is medium fine. Buoyancy is variable: Andiroba branca (varzea) floats, Andiroba vermelha (terra firme) does not float. Density at 12 % moisture content: 0.67 g/cm3.

Machining goes well, with a smooth result. Resawing can be sometimes disappointing because of the deformation. Some difficulties in planning in presence of interlocked grain. Pre-drilling is recommended. Tends to split in nailing. Finishing and gluing are reported to be good. Drying goes slowly with fewer problems. Low temperature and high humidity are recommended during drying.

Andiroba is moderately to poorly durable in ground contact.

The mahogany like timber can be used for furniture and flooring, stairs, mouldings, boxes and crates, joinery, panelling, seats, carpentry, interior window frames, veneer, ship building. Exterior application of the timber is restricted by the lower durability. Generally used as substitute for Mahogany (Swietenia spp.).
