In the wood industry, there is a relatively unassuming yet extremely powerful entity - the Iroko tree (Iroko).
It is known as "African Teak", "African Goldwood", and "The King of All Woods". It is the top hardwood of the genus Milicia of the family Anacardiaceae, with the scientific names Milicia excelsa and Milicia regia. In Africa, it is regarded as the "divine wood" by the locals; in the global wood market, it is the perfect substitute for teak, and even surpasses genuine teak in certain properties.
Today, we will thoroughly dissect this "golden wood" from Africa - from its origin, characteristics, uses, to identification, maintenance, and market trends. We will cover everything in this article!
Item | Details |
Chinese Name | Iroko, African Teak |
English Name | Iroko |
Scientific Name | Milicia excelsa / Milicia regia |
Family / Genus | Moraceae / Milicia |
Other Names | African Teak, Kambala, Mvule |
Origin | Tropical West Africa, including Cameroon, Republic of the Congo, Equatorial Guinea, Nigeria, Ghana, Côte d’Ivoire, etc. |
Tree Height | Up to 40 meters |
Trunk Diameter | Up to 2.0 meters or more |
Growth Period | Approximately 100 years or more to reach maturity |
1.2 Growth Environment The Iroko tree grows in the tropical rainforests of West Africa near the equator. There, the climate is hot and humid with distinct dry and wet seasons. It prefers sunlight and deep, fertile soil. Its growth is extremely slow - it takes a tree over a hundred years to reach maturity. It is precisely this "slow process for fine results" growth rhythm that endows it with unparalleled material stability.
1.3 Important Reminder: What is the relationship between it and the real teak?
Many people think that "African teak" is the same as teak, but they are completely wrong!
Real teak
(Teak): Scientific name Tectona grandis, belonging to the Rutaceae family and the Tectona genus. Mainly produced in Myanmar, Thailand, and India.
African teak
(Iroko): Scientific name Milicia excelsa, belonging to the Anacardiaceae family and the Milicia genus. Mainly produced in West Africa.
These two are not the same tree species at all! It's just that Iroko wood has very similar color, texture and properties to teak, so it is given the common name "African teak". However, in some aspects, Iroko wood even surpasses real teak - for example, it has higher hardness, greater strength, and is more affordable in price.
II. In-depth Analysis of Wood Properties
2.1 Macroscopic structural features
Irokomu is a diffuse-porous wood. The vessel cavities are visible to the naked eye. The main type is single vessel cavities, with a few radial compound vessel cavities (2-3) in a row. The filling bodies are abundant - this is the key structural feature that makes it highly resistant to water and moisture. The axial parenchyma is well-developed, presenting as wing-like and clustered wing-like shapes, and the wood ray density is moderate.
Property | Value |
Air-Dry Density | 0.62–0.72 g/cm³ (Medium Weight) |
Shrinkage (Radial) | Approx. 2.2% |
Shrinkage (Tangential) | Approx. 4.0% |
Bending Strength | Approx. 128.9 MPa |
Compression Strength Parallel to Grain | Approx. 76.1 MPa |
2.3 Six Core Advantages
✅ Advantage One: Ultimate Stability
The expansion and contraction rate of Irokomu wood is one of the smallest among all types of wood. Its fibers have a spiral structure, are tightly intertwined and very sturdy. Additionally, the wood is rich in natural oils, which form a protective film that effectively locks in moisture and is not affected by the dryness and humidity of the external air. Its crack resistance is at its peak, and it has no rivals!
✅ Advantage Two: Natural Pest and Mold Resistance
Irokomu wood is rich in iron and oil, naturally possessing the ability to resist pests, mold, termites, and acids and alkalis. In Africa, locals use it to build houses and make canoes, and after decades of exposure to wind and rain, it remains intact.
✅ Advantage Three: Beautiful Golden Color
The freshly cut surface is light brown or yellowish brown. Over time, it gradually oxidizes to a golden luster, becoming more and more attractive with use! The wood's cross-section has a charming golden luster, and after polishing, it is oily and shiny, with uniform color and straight grain, possessing great decorative value.
✅ Advantage Four: Excellent Processing Performance
It is easy to process, has strong adhesion, and has excellent glueing, planing, and painting properties. Especially for radial planing, it can achieve beautiful band-like patterns, making it an excellent material for making decorative veneers.
✅ Advantage Five: Extremely Strong Weather Resistance
Whether exposed to direct sunlight, rain, or salt water, Irokomu wood can handle it with ease. This is precisely why it is widely used in shipbuilding, outdoor construction, and bridges - the Zheng He fleet used similar performance wood to build ocean-going ships back then.
✅ Advantage Six: Environmentally Friendly and Healthy
The wood has no special odor and is naturally environmentally friendly. Its stable material does not release harmful substances, making it an excellent choice for making furniture and flooring.
2.4 Points to Note ⚠️
1. Prone to Dulling the Blade
: Due to the presence of calcium carbonate precipitates (commonly known as "stone-like") in the wood, it is prone to wearing down the blade during processing.
2. Sawdust Can Irritate the Skin
: Sawdust generated during processing may cause skin allergies. Protective measures should be taken during operation.
3. Need for Fillers
: Due to the presence of inclusions in the pipe holes, the pores usually need to be filled with fillers before surface coating.
4. May Change Color When Contacted with Dark Metals
: Do not keep it in long-term contact with dark metals (such as iron) as it may cause the wood to change color.
