PHYSICAL AND MECHANICAL PROPERTIES

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

• Density *: 0.38
• Monnin hardness *: 1, 1
• Coef. Volume shrinkage: 0.36%
• Stability in service: moderately stable to stable
• Total radial shrinkage: 2.9%
• Fiber saturation point: 29%
• Total tangential shrinkage: 5.0%

NATURAL DURABILITY AND IMPREGNABILITY OF WOOD

• Mushrooms: cl 5 – non durable / li>
• Insects of dry wood: susceptible; sapwood little or not distinct (risk in all the wood)
• Termites: class S – susceptible
• Impregnability: 3 – not very impregnable
• Biological risk class: 1 – out of contact with the ground, sheltered (no risk of humidification)

Sensitive to bluing and heating.

SAWING AND MACHINING

• Blunting effect: normal
• Teeth for sawing: ordinary or alloy steel
• Machining tools: ordinary

Crumbles during end machining and breaks during mortising. Mouth-porage recommended.

ASSEMBLY

• Nailing – Screwing: poor hold
• Gluing: correct

Gluing requires care: absorbent wood.

USES

Replaces poplar (Populus spp.) In many uses: light furniture.

• molding
• furniture
• crate-packing
