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
