Jatoba

Name

• Scientific: Hymenaea spp
• Spanish: Jatoba. Courbaril

Origin

Description of the wood

• Sapwood: Pinkish-white.

• Heartwood: Pinkish-brown to reddish-brown.

• Grain: Straight, sometimes slightly interlocked.

• Texture: Fine to medium.

• Characteristic defects: Growth stresses and stone inclusions.

Impregnation

• Sapwood: Moderately impregnable
• Heartwood: Poorly impregnable

Mechanization

• Sawing: No problems other than its hardness and some abrasiveness.

• Drying: Medium to slow. Slight risk of warping and cracking.

• Planing: Difficult due to its hardness, abrasiveness, and the risk of warping in pieces with interlocked grain. Machining should be done very slowly.

• Gluing: The tannins hinder good adhesion.

• Nailing and screwing: Due to its hardness, pre-drilling is recommended.

• Finishing: No special problems.

Applications

• Fine interior and exterior furniture and joinery.

• Turned and bentwood furniture.

• Interior carpentry: doors, stairs, paneling, moldings, baseboards, wainscoting, parquet flooring.

• Exterior carpentry: doors and windows.

• Interior and exterior structural carpentry.

• Decorative veneers.

• Cooperage.

Mechanical properties

• Static bending strength: 1,338 kg/cm²

• Modulus of elasticity: 180,000 kg/cm²
• Compressive strength parallel to the axis: 750 kg/cm²
