IDENTIFICATION DU BOIS
Description anatomique du bois
Wood diffuse porous. Vessels solitary and in short radial multiples. Tangential diameter of vessel lumina 100 micras or less (very small). Occasionally vessels with colored deposits. Occasionally white deposits in heartwood vessels. Vessels per mm2 more than 2 Axial parenchyma in marginal or in seemingly marginal bands. Paratracheal axial parenchyma scanty and/or vasicentric. Occasionally axial parenchyma storied. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. 3 to 4 cells per parenchyma s 4 to 10 rays per mm (medium). Rays non-storied. Larger rays more than 4 seriate. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Fibers with simple to minutely bordered pits.

Grain
The grain is typically straight, sometimes interlocked.
Texture
The wood has a medium to fine texture.
Luster
The wood has medium to high luster.
Durabilité naturelle
The heartwood is resistant to decay fungi attack and to termites, but it is less resistant to marine borers.
Index de durabilité naturelle (1 = Très élevée, 7 = Très faible)
2
Résistance à l'imprégnation
It is very difficult to treat, but for most applications preservative treatments are not required.

OUVRABILITÉ
Sciage
Peltogyne is reported to be moderately difficult to saw. Tools usually require frequent sharpening.
Coupe de placage de déroulage
This species is interesting for slicing, thermal treatments are recommended.
Placage tranche
This species is interesting for slicing, thermal treatments are recommended.
Effet d'émoussement
Cutting tools may be gummed up if they are not very sharp. Blunting is rated as moderate.
Usinage
Peltogyne is reported to be moderately difficult to work in most machining operations including planing, turning, boring, and molding. They respond rather poorly to ordinary tools, and working with dull cutters may cause the wood to heat up.
Rabotage
A reduction of the cutting angle to 15 degrees is required, when wavy or interlocked material is present, to obtain satisfactory results in planing.
Tournage
30
Perçage
Boring is difficult, the wood has a tendency to burn
Mortaisage
To get good results in mortising end support is needed.
Clouage
The wood requires to be pre-bored, but nail-holding capabilities are reported to be good.
Collage
The material is reported to be easy to glue.
Ponçage
The material is reported to be fairly difficult to sand.
Finissage
Organic solvents remove the characteristic purple color. To preserve the natural color, wax finishing is recommended.
Teinture
For this species water-based finishes are reported to hold color better. The use of spirit finishes may remove the purple coloring in the wood.
Polissage
Polishing properties are reported to be rather good.
Cintrage à la vapeur
The wood steam bends fairly well.
Compatibilité avec outils manuels
Response to hand tools is reported to be only fair.
