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
• Coef. Volume shrinkage: 0.64%
• Stability in service: not very stable
• Total radial shrinkage: 6.5%
• Fiber saturation point: 23%
• Total tangential shrinkage: 8.7%

(*: 12% humidity)

NATURAL DURABILITY AND IMPREGNABILITY OF WOOD

• Mushrooms: cl 1 – very durable
• Dry wood insects: durable; distinct sapwood (risk limited to sapwood)
• Termites: class D – durable
• Impregnability: 3-4 – little or no impregnation
• Biological risk class: 4 – in contact with soil or fresh water

Due to its high density and high silica content, it naturally covers biological risk class 5 (use in marine environment or brackish water).

SAWING AND MACHINING

• Blunting effect: significant
• Teeth for sawing: stellate teeth
• Machining tools: tungsten carbide

Requires power. Quite high to high blunting effect (silica). Dust can irritate mucous membranes.

ASSEMBLY

• Nailing – Screwing: good hold, pre-boring necessary
• Gluing: correct

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

USES

A substitute for the Makoré

• exterior and interior carpentry
• paneling
• parquet
• stairs
• furniture
• sleepers
• turned items
• sculpture

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

REACTION TO FIRE

• French conventional classification: thickness> 14 mm: M.3 (moderately flammable) thickness <14 mm: M.4 (easily flammable)
• classification according to euroclasses: D s2 d0 This default classification concerns solid woods meeting the requirements of standard NF EN 14081-1 appendix C (May 2006), used in vertical walls. Namely structural wood, classified, with a minimum average density of 0.35 and a minimum thickness of 22 mm.
