SIPO

Family : MELIACEAE
Scientific name : ENTANDROPHRAGMA UTILE

WOOD DESCRIPTION

  • Reference colour: red brown
  • Sapwood: distinct property
  • Grain: medium
  • Thread: counter-thread
  • Counter-wire: light

Wood pinkish brown to slightly purplish red brown, nuanced with moiré reflections. Banded appearance on quarter. Irregular thread.

PHYSICAL AND MECHANICAL PROPERTIES

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

  • Density*: 0.62 – Coin hardness*: 3.0
  • Coef. Volume Shrinkage: 0.42%
  • In-service stability: moderately stable to stable
  • Total radial shrinkage: 4.6%
  • Fibre saturation point: 30 %
  • Total tangential withdrawal: 6.4%
    (*: 12% moisture)

Variable hardness: semi-hard softwood.

NATURAL DURABILITY AND IMPREGNABILITY OF WOOD

  • Mushrooms: cl 2-3 durable to moderately durable
  • Dry wood insects: durable; distinct sapwood (limited risk to sapwood)
  • Termites: Class M – moderately sustainable
  • Impregnability: 4 – non impregnable
  • Biological hazard class: 2 – out of contact with soil, sheltered (risk of humidification)

SAWING AND MACHINING

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

Tendency to tear due to contra-wire.

ASSEMBLY

  • Nailing – Screwing: good hold
  • Bonding: correct

Gluing requires care: wood can stain.

END-USES

A mouth-porage is recommended to obtain a better finish.

  • furniture
  • exterior and interior carpentry
  • panelling
  • moulding
  • light craft
  • parquet
  • stairs

Main known uses to be validated by an implementation in compliance with the rules of the art. Important note: some uses are mentioned for information.
