Provenance

Description of the wood

• Sapwood: Yellowish white.
• Heartwood: Yellowish brown that turns reddish brown with light.
• Fiber: Straight, often slightly intertwined.
• Grain: Medium to coarse.

Impregnation

• Sapwood: Impregnable
• Heartwood: Non-impregnable

Mechanization

• Sawing: No difficulties except for some abrasiveness of calcareous deposits that it contains.
• Drying: Medium to slow. Small risks of deformations and fendas.
• Planning: Relatively well, except for its abrasiveness and the risk of repelling when it has interlaced fiber.
• Gluing: Problems with casein glues.
• Nailing and screwing: No problems.
• Finish: It has tannins that can inhibit the drying of oxidizing varnishes, such as polyurethanes or others.

Applications

• Outdoor furniture, parks and urban gardens.
• Interior carpentry, doors, stairs, coatings, mouldings, skirting boards, friezes, flooring.
• Exterior carpentry, doors and windows.
• Carpentry of interior and exterior assembly.
• Decorative plates.

Mechanical properties

• Resistance to static flexion 955 kg/cm2

• Elasticity module 105,000 kg/cm2

• Resistance to compression 540 kg/cm2

• Parallel tensile strength 800 kg/cm2

Notes

- The sapwood is advisable not to use. In some areas and erroneously they call it Teak.
- When sawn, it presents different colorations that are posterionnente.
