Impregnabilidad
- Sapwood: Capable of being impregnated
- Heartwood: No capable of being impregnated
Propiedades mecánicas
- Resistance to static flexion 1,350 kg/cm2
- Elasticity module 154,000 kg/cm2
- Resistance to compression 670 kg/cm2
Mecanización
- Sawing process: the hardness and high silica contents wear away tools and so makes sawing process difficult. In addition to that, oils can also produce irritation.
- Drying process: From low to very low speed. Little risk of deformation and crack formation.
- Planing process: Appart from hadness and silica difficulties, risk of repelling is very frequent due to the intertwined fibers.
- Gluing process: No difficulties arise excepting on very oily surfaces. In these cases, previous cleaning can be required.
- Nailing and screwing process: Pre-drilling is required
- Finish: No difficulties
