Impregnabilidad
  • Sapwood: capable of being impregnated.
  • Heartwood: low capacity of being impregnated.
Propiedades mecánicas
  • Resistance to static flexion 1,090 kg/cm2.
  • Elasticity module 126,000 kg/cm2.
  • Resistance to compression 540 kg/cm2.
Mecanización
  • Sawing process: high potency is required.
  • Drying process: easy and considerably slow. Risk of collapse, cementation and inside and outside crack formation.
  • Planing process and other processes: risk of repelling appart from potency requirement problems.
  • Gluing process: easy.
  • Nailing and screwing process: pre-drilling is required in order to facilitate penetration and prevent breaks.
  • Finish: easy

  • Dimensional stability
  • - Volumetric contraction coefficient 0.49 % nervous wood.
  • - Relation between contractions 2.06% tendency to deformity.
  • Hardness (Chaláis-Meudon) 4.5 semi-hardwood.
Observaciones
  • La seva principal diferència amb el tou està en el color, el maple dur té un blanc brillant
