Mukurwe
Scientific name: Cynometra alexandri
Overview
Mukurwe is a very dense and durable hardwood native to East Africa. It is often compared to ebony due to its dark coloration and fine texture. The wood is extremely strong and resistant to wear, making it suitable for demanding applications, though its density makes it more difficult to work.
Quick Facts
- Common Name: Mukurwe
- Scientific Name: Cynometra alexandri
- Region: African Hardwoods (East Africa)
- Tree Size: 80–100 ft tall, 3–5 ft trunk diameter
- Average Dried Weight: 65 lbs/ft³ (1,040 kg/m³)
- Janka Hardness: 2,200 lbf
- Color: Dark brown to purplish brown
- Grain: Interlocked
- Texture: Fine to medium
Identification Characteristics
Mukurwe is known for its dark coloration and dense structure. It may show subtle streaking and a slightly polished appearance when finished.
Key identification traits include:
- Dark brown to purplish coloration
- Fine to medium texture
- Interlocked grain
- Very dense and heavy
Working Properties
Mukurwe is difficult to work due to its density and grain structure. It requires sharp tools and careful handling to avoid tearout.
- Difficult to machine
- High tool wear
