MOABI

Family : SAPOTACEAE
Scientific name : BAILLONELLA TOXISPERMA – MIMUSOPS DJAVE

WOOD DESCRIPTION

  • Reference colour: reddish brown
  • Sapwood: very distinct
  • Grain: fine
  • Thread: straight or counter-thread
  • Counter grain: light

Pinkish brown to reddish brown wood, more or less dark and finely grained. Satin appearance on the quarter.

PHYSICAL AND MECHANICAL PROPERTIES

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

  • Density*: 0.87
  • Monnin* hardness: 6.8
  • Volume shrinkage coefficient: 0.64
  • Stability in service: not very stable
  • Total radial shrinkage: 6.5
  • Fibre saturation point: 23
  • Total tangential shrinkage: 8.7
    (*: 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: 3-4 – little or no impregnability

Because of its high density and high silica content, it naturally covers biological risk class 5 (for use in marine environments or brackish water).

SAWING AND MACHINING

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

Requires power. Fairly high to high de-sharpening effect (silica). Dust can irritate mucous membranes.

ASSEMBLY

  • Nailing – Screwing: good hold, pilot holes required
  • Gluing: correct

Tends to split when nailed. Nailing requires care (dense wood).
