DABEMA

Family : FABACEAE-MIMOSOIDEAE
Scientific name : PIPTADENIASTRUM AFRICANUM

WOOD DESCRIPTION

  • Colour reference: yellow brown
  • Sapwood: distinct property
  • Grain: coarse – Wire: strut
  • Counter-wire: accused

Light brown to golden brown, sometimes banded on quarter. Smell of ammonia in green or on rehydrated woods.

PHYSICAL AND MECHANICAL PROPERTIES

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

  • Density*: 0.70
  • Coin hardness*: 4.4
  • Coef. Volume Shrinkage: 0.55%
  • Stability in service: moderately stable
  • Total radial shrinkage: 3.8%
  • Fiber saturation pt: 27%
  • Total tangential withdrawal: 8.5%
    (*: 12% moisture)

NATURAL DURABILITY AND IMPREGNABILITY OF WOOD

  • Mushrooms: Moderately durable cl 3
  • Dry wood insects: durable; distinct sapwood (limited risk to sapwood)
  • Termites: class D – sustainable
  • impregnability: 3 – impregnable
  • Resistance to fungi: medium to good

SAWING AND MACHINING

  • Desafflant effect: normal
  • Toothing for sawing: ordinary or alloy steel
  • Machining tools: ordinary

Very irritating dust. The flow on quarter is recommended to reduce the risk of deformations.

ASSEMBLY

  • Nailing – Screwing: good hold
  • Bonding: correct

Risk of cracks at the ends

END-USES

Sometimes the presence of resin can interfere with the adhesion of finishing products. Sanding requires care. Mouth-porage necessary for a good finish.

  • heavy frame
  • stairs (inside)
  • furniture
  • parquet (heavy or industrial)
  • Exterior cladding
  • framework
  • bottom of vehicle or container

Can be used as a substitute for CHENE (QUERCUS SPP.) for certain jobs.
Main known uses to be validated by an implementation in compliance with the rules of the art.
