Iroko

Name

• Scientific: Clorophora excelsa Benth. & Hooff.: C. regia A. Chev
• Spanish: Iroko. African Iroko

Origin

Description of the wood

• Sapwood: Yellowish-white.

• Heartwood: Yellowish-brown, turning reddish-brown in the light.

• Grain: Straight, often slightly interlocked.

• Texture: Medium to coarse.

Impregnation

• Sapwood: Impregnable
• Heartwood: Not impregnable

Mechanization

• Sawing: No difficulties except for some abrasiveness from the calcareous deposits it contains.

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

• Planing: Relatively good, except for its abrasiveness and the risk of splitting when the grain is interlocked.

• Gluing: Problems with casein glues.

• Nailing and screwing: No problems.

• Finishing: Contains tannins that can inhibit the drying of oxidizing varnishes, such as polyurethanes or others.

Applications

• Outdoor furniture for parks and urban gardens.

• Interior joinery: doors, stairs, paneling, moldings, baseboards, wainscoting, decking.

• Exterior joinery: doors and windows.

• Structural joinery for interior and exterior use.

• Decorative veneers.

Mechanical properties

• Static bending strength: 955 kg/cm²

• Modulus of elasticity: 105,000 kg/cm²

• Compressive strength parallel to the axis: 540 kg/cm²
• Tensile strength parallel to the axis: 800 kg/cm²

To be considered

- It is recommended not to use the sapwood. In some areas, it is incorrectly called teak.

- When sawn, it displays various colors that even out over time.
