African Padauk

African Padauk Timber - EO DESIGN by Ernesto Oñate

Scientific Name

Pterocarpus soyauxii

Pterocarpus buettneri Taub,

P. Osun Craib.

P. Tinctorius Welw.

 

Timber type

Tropical.

 

Origin

Africa. It is original of the tropics of Central and West Africa, from Nigeria to the Congo region and Southern Angola.

 

Description

  • Sapwood: Whitish.
  • Heartwood: Intense red that darkens into dark brown due to light effects. It frequently has dark brown streaks.
  • Fiber: Straight. Slightly intertwined fibers are very frequent.
  • Grain: Medium size to rough.
  • Defects: White deposit bags.

Physical Properties

  • Apparent density at 12 % humidity: 740 kg/m3. Heavy Wood.
  • Dimensional stability:
    • Volumetric contraction coefficient 0,36 %. Stable Wood.
    • Relation between contractions 1,60 %. No tendency to deformity.
  • Hardness (Chaláis-Meudon) 6,9. Hard wood.

 

Durability

Very durable.

 

Aplications

  • Interior furniture and cabinet work.
  • Exterior furniture and cabinet work.
  • Carved and turned furniture.
  • Interior carpentry: doors, paneling, molding, baseboards, friezes and stairs.
  • Exterior carpentry: doors and windows.
  • Carpentry.
  • Decorative panels.

 

Mechanical Properties

  • Resistance to static flexion: 1,450 kg/cm2.
  • 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: Apart from hardness 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.

 

Capacity of being Impregnated

  • Sapwood: Capable of being impregnated.
  • Heartwood: Medium capacity of being impregnated.
