Ekaba
Species profile
The wood is pinkish brown and does not have clearly demarcated sapwood. The grain is straight or interlocked and the texture is medium. Possible presence of wind shakes.

The blunting effect is normal, peeling is reported to be good, and slicing is not recommended or without interest. Risks of grain tearing in presence of interlocked grain; a reduced cutting angle is then recommended. Nailing is poor and gluing is correct. Ekaba dries normal to slowly. T. bifoliolata has lower physical and mechanical properties than T. tubmaniana.

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

Ekaba can be used for several applications such as:
• interior: e.g. furniture, interior joinery, panelling, veneer, light carpentry, moulding, boxes and crates, formwork
• exterior: e.g. wood frame house, exterior joinery, panelling
