Balsa

Name

• Scientific name: Achroma lagopus
• Spanish name: balsa

Origin

Description of the wood

• Sapwood ranges from creamy white to very pale pink
• Heartwood ranges from creamy white to very pale pink
• Straight grain
• Coarse texture
• Defects: Not recommended for veneer by peeling or flat cutting.

Impregnation

• Sapwood: impregnable
• Heartwood: poorly impregnable

Mechanization

• Sawing: Easy.

• Drying: Between slow and normal. Air drying is not recommended.

• Gluing: No problems. Note its high absorption rate.

• Nailing and screwing: Nails penetrate well but hold poorly.

• Finishing: Apply a wood sealer before finishing.

Applications

• Scale models, miniature models.

• Floats, harnesses, lifeboats, signaling buoys.

• Toys, special packaging.

• Sandwich panels.

• Sound insulation.

Mechanical properties

• Static bending strength: 190 kg/cm²

• Modulus of elasticity: 26,800 kg/cm²
• Compressive strength parallel to the axis: 100 kg/cm²
• Tensile strength parallel to the axis: 26 kg/cm²

To be considered

- Wood from South America, especially from the Pacific region.
