Black Bean
Black Bean (Castanospermum australe), also known as Moreton Bay Chestnut, is a dense and durable Australian hardwood valued for its unique dark brown to black streaks set against a lighter background. The timber has a fine to medium texture with a straight to slightly interlocked grain, making it visually distinctive and highly sought after for fine furniture, joinery, and decorative applications. Black Bean is moderately hard but workable, allowing for smooth machining and finishing. While it is naturally resistant to termites and decay, it is primarily used indoors due to its moderate weathering properties. Its striking aesthetic makes it a popular choice for statement pieces, high-end cabinetry, and musical instruments.
Key Features:
- Rich, dark brown to black streaks with lighter contrasts
- Fine to medium texture with straight to slightly interlocked grain
- Durable and moderately hard, suitable for fine woodworking
- Resistant to termites and decay
- Ideal for statement pieces in furniture and joinery
Common Uses:
- High-end furniture and cabinetry
- Decorative veneers and paneling
- Musical instruments
- Specialty woodturning and carving
- Flooring and inlays
Sustainability:
Black Bean is a slow-growing tree, and its availability is limited compared to plantation-grown species. While not commonly plantation-grown, sustainable sourcing practices help protect its natural populations. Harvesting is carefully managed to ensure minimal impact on Australian forests.
Density & Hardness:
- Density: Approximately 800 kg/m³
- Janka Hardness: Around 5.3 kN (moderately hard, suitable for fine detail work)
