Koto
Scientific name: Pterygota macrocarpa
Overview
Koto is a light-colored hardwood native to West Africa, known for its pale yellow appearance and relatively lightweight structure. It is commonly used in interior applications where a uniform, clean look is desired.
While not as dense or durable as many tropical hardwoods, Koto offers good workability and a consistent texture, making it suitable for paneling and light construction.
Quick Facts
- Common Name: Koto
- Scientific Name: Pterygota macrocarpa
- Region: African Hardwoods (West Africa)
- Tree Size: 100–130 ft tall, 3–5 ft trunk diameter
- Average Dried Weight: 34 lbs/ft³ (545 kg/m³)
- Janka Hardness: 420 lbf
- Color: Pale yellow to creamy white
- Grain: Straight to slightly interlocked
- Texture: Medium to coarse
Identification Characteristics
Koto is easily recognized by its pale yellow coloration and relatively uniform appearance. The grain is typically straight, though slight interlocking may occur.
It has a somewhat coarse texture and lacks the dramatic figure found in many darker tropical hardwoods.
Key identification traits include:
- Pale yellow to cream-colored heartwood
- Straight to slightly interlocked grain
- Moderate to coarse texture
- Lightweight compared to many tropical hardwoods
Working Properties
Koto is generally easy to work, though its coarse texture can affect surface smoothness.
- Machines easily with standard tools
- May require filling for a smooth finish
- Glues and finishes well
- Accepts paint and stain readily
- Moderate stability in service
Safety Note
Dust may cause mild irritation to the skin and respiratory system. Standard protective measures are recommended.
Common Uses
Koto is typically used in applications where light color and ease of workability are important.
- Interior paneling and wall coverings
- Light furniture and cabinetry
- Veneer and plywood
- Moldings and trim
- General interior joinery
Sustainability & Notes
Koto is not listed under CITES, though sustainable sourcing is encouraged due to regional harvesting pressures.
