PADOUK

Family : FABACEAE
Scientific name : PTEROCARPUS SOYAUXII / OSUN

WOOD DESCRIPTION

  •  Reference colour: red
  • Sapwood: quite distinct
  • Grain: coarse
  • Grain: straight or counter-grain
  • Counter grain: light

The wood is bright red, turning purplish brown in the light.

PHYSICAL AND MECHANICAL PROPERTIES

These properties can vary significantly depending on the origin and growing conditions of the wood.

  • Density*: 0.79
  • Monnin* hardness: 8.3
  • Volume shrinkage coefficient: 0.44
  • Stability in service: stable
  • Total radial shrinkage: 3.2
  • Fibre saturation point: 21
  • Total tangential shrinkage: 5.0
    (*: 12% moisture content)

NATURAL DURABILITY AND IMPREGNABILITY OF WOOD

  • Fungi: class 1 – very durable
  • Dry wood insects: durable; sapwood distinct (risk limited to sapwood)
  • Termites: class D – durable
  • Impregnability: 2 – moderately impregnable
  • Biological risk class: 4 – in contact with soil or fresh water

It naturally only covers biological risk class 5 (use in a marine environment or brackish water) for temperate and cold environments).

SAWING AND MACHINING

  • Sharpening effect: fairly high
  • Sawing teeth: stellite-tipped teeth
  • Machining tools: tungsten carbide

Dust can be irritating. Requires power. Sometimes difficult due to counter-wire.

ASSEMBLY

  • Nailing – Screwing: good hold
  • Gluing: correct

Pilot holes are necessary because of the risk of splitting, particularly in small sizes. Gluing requires care (dense wood).

END-USES

  • hydraulic works
  • flooring
  • cross-members
  • vehicle or container bottoms
  • shipbuilding
  • turned items
  • exterior and interior joinery
  • staircases
  • sculpture
  • exterior cladding

Main known uses to be validated by application in accordance with the rules of the trade. Important note: some uses are listed for information only.
