Ilomba
Species profile
The wood is pinkish brown to light brown. Possible presence of brittleheart and a strong tendency to shakes. It does not have demarcated sapwood. The grain is straight and the texture is coarse. Density at 12 % moisture content: 0.49 g/cm3.

The blunting effect is normal; peeling is reported to be good and slicing is not recommended or without interest. Quartersawn is recommended in order to reduce the risks of distortion during drying. Nailing is poor and gluing is correct. Tends to split in nailing. Ilomba dries normal. The drying is difficult for thickness > 54 mm. Steaming strongly recommended before kiln drying (T=95ºC, Humidity=100 %) during 48 hours.

Ilomba is not durable to fungi and is susceptible to dry wood borers; sapwood not or slightly demarcated (risk in all the wood).

Ilomba can be used for several applications such as:
• interior: e.g. furniture, panelling, veneer, pencils, boxes and crates, moulding, joinery
• exterior: e.g. panelling
