Physical Properties:

  • Apparent density at 12% humidity: 850 kg/m3. Very heavy Wood.
  • Dimensional stabilitly:
    • Volumetric contraction coefficient: 0,54%. Very nervous wood.
    • Relation between contractions: 1,6%. No tendency to deformity.
  • Hardness (Chaláis-Meudon): 8,1. Very hard Wood.

 

Durability

Durable.

 

 

Aplications:

  • Interior furniture and cabinet work.
  • Exterior furniture and cabinet work.
  • Carved and turned furniture.
  • Interior carpentry: doors, stairs, paneling, molding, baseboards, friezes and parquet flooring.
  • Exterior carpentr: doors and windows.
  • Decorative panels.

 

Mechanical Properties:

  • Resistence to static flexion: 1,800 kg/cm2.
  • Elasticity module: 180,000 kg/cm2.
  • Resistance to compression: 800 kg/cm2.

 

Mecanization:

  • Sawing process: Ordinary difficulties due to hardness and abrasivity.
  • Drying process: Slow. Low risk of deformation and high risk of crack formation.
  • Planing process: Difficulties due to hardness and abrasivity.
  • Gluing process: Tannins hamper proper adherence.
  • Nailing and screwing process: Pre-drilling is required due to hardness.
  • Finish: No difficulties.

 

Capacity of being Impregnated:

  • Sapwood: Medium capacity of being impregnated.
  • Heartwood: No capable of being impregnated.
