Khaya

Denominación científica:
Scientific name: Khaya spp <br />
Procedencia geográfica:
Center, west and east of Africa.
  • Sapwood: pink white.
  • Heartwood: varies from pink brown to light red that darkens with the light effects.
  • Fiber: straight, usually intertwined and of small to medium size.
  • Grain: medium size.
  • Characteristic defects: growth tensions, soft core.

Impregnabilidad
  • Sapwood: medium capacity of being impregnated.
  • Heartwood: no capable of being impregnated.
Propiedades mecánicas
  • Resistance to static flexion 760 kg/cm2.
  • Elasticity module 94,000 kg/cm2.
  • Resistance to compression 460 kg/cm2.
  • Resistance to parallel traction of fibers 600 kg/cm2.
Mecanización
  • Sawing process: easy, although there is a risk of deformation due to growth tensions.
  • Drying process: easy and fast. Low risk of deformation, with mainly intertwined wood.
  • Planing process: risk of repelling with intertwined fiber pieces.
  • Gluing process: no difficulties.
  • Nailing and screwing process: easy.
  • Finish: no difficulties.
Propiedades físicas
  • Apparent density at 12% humidity 510 kg/m3 semi-light.
  • Dimensional stability
  • Volumetric contraction coefficient 0.41 % stable wood.
  • Relation between contractions 1.52% no tendency to deformity.
  • Hardness (Chaláis-Meudon) 1.9 softwood.
Observaciones
  • També se la coneix amb el nom de Samanguila.
  • Clara diferència de color entre l'albura i el duramen.
  • Com que pot tenir la fibra entrellaçada, després del raspallat pot seguir quedant el que anomenem “repel·lo”, ja que les fulles no tallen bé la fibra i ho que fan és arrencar-la.
