Wood golden brown to light red brown, sometimes with darker veins. Afzelia bipidensis can |
often be identified by the presence of yellow powder at the heart. |
|
|
|
Physical and mechanical properties are based on mature heartwood specimens. These properties can vary greatly depending on |
origin and growth conditions |

| NATURAL DURABILITY AND TREATABILITY |
Fungi and termite resistance refers to end-uses under temperate climate. |
Except for special comments on sapwood, natural durability is based on mature heartwood. |
Sapwood must always be considered as non-durable against wood degrading agents. |
|
| Fungi: |
Class 1 - very durable |
|
|
Durable; sapwood demarcated (risk limited to sapwood) |
|
| Termites: |
|
|
|
| Use class*: |
4 - in ground or fresh water contact |
This species is listed in the European standard NF EN 350-2. |
According to the European standard NF EN 335, performance length might be modified by the |
intensity of end-use exposition. |

This schedule is given for information only and is applicable to thickness < 38 mm. |
It must be used in compliance with the code of practice. |
For thickness from 38 to 75 mm , the air relative humidity should be increased by 5 % at each step. |
For thickness over 75 mm , a 10 % increase should be considered. |
|
Difficulties in extracting moisture from the heart of pieces. Slow drying necessary (3 to 5 |
months). |
|
|
|
|
|
|
|
|
Not recommended or without interest |
|
|
Peeling recommended only for decorative veneer. Sawdust may cause irritations. Some |
difficulties due to interlocked grain (tearing). |
|
|
Good but pre-boring necessary |
|
|
Correct (for interior only) |
|
|
Tends to split when nailing. Gluing may be difficult due to the presence of wood extractives |
|
Main known end-uses; they must to be implemented according to the code of practice. |
Important remark: some end-uses are mentionned for information (traditional, regional or ancient end-uses). |
|
Yellow powder often visible in areas near the heart contain substances that might hinder varnish |
Filling is recommended to obtain a good finish |
Bridges (parts in contact with water or ground) |
Ship building (planking and deck) |
Bridges (parts not in contact with water or ground) |
Cabinetwork (high class furniture) |
Current furniture or furniture components |
Industrial or heavy flooring |
Resistant to one or several acids |
