Capacity of being impregnated
- Sapwood: Medium capacity of being impregnated
- Heartwood: No capable of being impregnated
Mechanical properties
- Resistance to static flexion 1,150 kg/cm2 &;8226; Elasticity module 110,000 kg/cm2
- Resistance to compression 550 kg/cm2
- Resistance to parallel traction 1,050 kg/cm2
Mechanization
- Sawing process: No difficulties.
- Drying process: Speed can vary from medium to high speed. Little risk of deformation and crack formation.
- Planing process: No difficulties appart from risk of repelling produced by the intertwined fibers.
