Padauk
Scientific name:
Pterocarpus buettneri Taub.; P. Osun Craib; P. Tinctorius Welw
Geographic origin:
Africa
- Sapwood: cream-coloured.
- Heartwood: intense rojo colour that darkens into dark grey due to light effects. It frequently has dark grey streaks.
- Fiber: Straight. Slightly intertwined fibers are very frequent.
- Grain: medium size to rough.
- Defects: white deposit bags

Capacity of being impregnated
- Sapwood: Capable of being impregnated
- Heartwood: Medium capacity of being impregnated
Mechanical properties
- Resistance to static flexion 1,450 kg/cm2 &;8226; Elasticity module 124,000 kg/cm2
- Resistance to compression 650 kg/cm2
Mechanization
- Sawing process: Hard and with some abrasive effects.
- Drying process: Medium to low speed. Little risk of deformation and crack formation.
- Planing process: Appart from hadness and abrasability difficulties, risk of repelling is very frequent in those cases of intertwined fibers. Suitable for carving and bending
- Gluing process: Certain difficulties due to the oil content.
- Nailing and screwing process: Pre-drilling is required
- Finish: No difficulties
Physical properties
- Apparent density at 12% humidity 740 kg/m3 heavy wood
- Dimensional stability
- - Volumetric contraction coefficient 0.36 % stable wood.
- - Relation between contractions 1.6 no tendency to deformity
- Hardness (Chaláis-Meudon) 6.9 hardwood
