Non-standard Names Black Rosewood or African Black Rosewood Identification Key Points Bark: Rough, scaly, warped and peeling off, leaving shallow pits. Heartwood: Unique golden-brown, turning reddish-brown with age. Pores: Inclined in radial/oblique arrangement. Timber: Extremely hard and heavy. Macroscopic Structure Growth Type: Diffuse-porous wood. Pores: Few, medium-sized (visible to the naked eye); mainly single pores, with a few radial multiple pores (2–3 pores); containing brown gum. Axial Parenchyma: Visible to the naked eye, in short aliform and a few confluent-aliform forms. Wood Rays: Obvious under a magnifying glass, slightly dense and narrow. Morphological Characteristics Tree Size: Large 乔木 (trees), up to 50–60 m tall, with straight and full trunks, most with a diameter of 1.0–1.5 m; low buttress roots. Climate Influence: Grown in the unpredictable tropical rainforests of the Ashanti Plateau, where equatorial average temperatures often exceed 40°C and precipitation varies significantly. This complex climate endows the wood with wide adaptability, stability, and unique environmental charm. Color & Texture: Wood color leans toward black-yellow with black streaks; heartwood shows significant color variation, with some cores tending to yellow, drying to yellowish-brown or dark brown. Hard texture, slightly oily, excellent stability, and natural corrosion resistance. Distribution Range Geographic Range: Native to tropical West Africa, commonly imported from Ghana, the Congo, etc. Major Sources: Abundant in Ghana, the Congo, and Atlantic coastal regions like Mozambique; 少量 (rarely) found in Equatorial Guinea and Madagascar. Ghanaian varieties with yellow-brown and dark stripes are particularly prized. Cross Section Heartwood & Sapwood: Clearly differentiated. Heartwood: Golden-brown with a greenish tint, later turning reddish-brown; some producing areas have dark fine stripes. Sapwood: Light pink, 5–7 cm wide. Growth Rings: Not obvious. Bark Thickness: 0.5–1.0 cm, rough, hard, and not easily broken. Outer Bark: Grayish-white to grayish-brown, scaly, warped, and peeling, leaving shallow pits. Inner Bark: Purple-red; phloem fibers well-developed, easily torn into hemp-like short fibers. Timber Properties Luster: Shiny. Texture: Interlocked. Structure: Dense. Hardness & Weight: Extremely hard and heavy, high strength. Processing: Requires high-hardness alloy saw blades; good turning, gluing, and polishing performance. Durability: Highly resistant to termites, extremely durable and wear-resistant. Density: Air-dry density > 1.0 g/cm³. Main Uses High-Value Construction: Classical heavy buildings, pavilions, halls, temples. Furniture & Decor: High-end furniture, flooring. Industrial Applications: Vehicles, yachts, shipbuilding. Notes "乔木" retained in Chinese for botanical accuracy, translated as "trees" in English. Technical terms follow international forestry standards (e.g., "diffuse-porous wood", "axial parenchyma"). Regional names (e.g., "Ghana", "Congo") use English with Chinese equivalents in parentheses for clarity where necessary. Global Bill of Lading Available for Sale
