Species: Alep

Species profile
The wood is yellow brown with clearly demarcated sapwood. The wood turns to dark brown with air and dark veins are more or less numerous. The grain is straight and the texture is fine.

The blunting effect is fairly high and peeling and slicing is not recommended or without interest. Requires power. Logs must be sawn quickly after felling (cracks during drying). Nailing is good but pre-boring is necessary. Gluing is correct for interior only and must be done with care (very dense wood). Drying rate is slow.

Alep is very durable to fungi and it is durable to dry wood borers; sapwood demarcated (risk limited to sapwood). Due to its high specific gravity and hardness, this species naturally covers the biological hazard class 5 (end-uses in marine environment and brackish water).

This exclusive species is typical used for several purposes such as:
• exterior: e.g. bridges, vehicle or container flooring, sleepers, heavy carpentry, posts

• CIRAD Forestry Department
