Capacity of being impregnated
- Sapwood: capable of being impregnated.
- Heartwood: no capable of being impregnated.
Mechanical properties
- Resistance to static flexion 1.100 kg/cm2.
- Elasticity module 109.000 kg/cm2.
- Resistance to compression 510 kg/cm2.
Mechanization
- Sawing process: easy, except in the presence of silica, a situation that causes fast wear of saws and irritating dust.
- Drying process: medium speed. Medium risk of deformation and crack formation.
- Planing process: no difficulties excepting those named cases of silica and the risk of repelling on pieces of intertwined wood.
- Gluing process: no difficulties.
- Nailing and screwing process: no difficulties.
- Finish: no difficulties, except in case of resin exudations , they can be usual .
Physical properties
- Apparent density at 12% humidity 600 kg/m3 fom semi-light wood to semi-heavy wood.
- Dimensional stability
- - Volumetric contraction coefficient 0.43 % variation from stable wood to slightly nervous wood.
- - Relation between contractions 1.61 no tendency to deformity.
- Hardness (Chaláis-Meudon) 3.6 semi-hardwood.
Observations
- Albura color clar i duramen més fosc
- En ocasions, erròniament, li diuen Cedre
- Existeixen variacions de color importants depenent de la procedència
- Té una olor molt agradable de cedre, com indica el seu nom, però amb el temps desapareix.
