Massaranduba
Scientific name: Manilkara bidentata
Overview
Massaranduba is an extremely dense South American hardwood known for its strength, durability, and deep reddish-brown coloration. Native to Central and South America, it is commonly used in applications where resistance to wear, moisture, and impact is critical.
Often marketed as “Brazilian Redwood,” Massaranduba is valued for its toughness and long service life, particularly in exterior and heavy-duty uses.
Quick Facts
- Common Name: Massaranduba, Bulletwood
- Scientific Name: Manilkara bidentata
- Region: South American Hardwoods (Amazon Basin – Brazil, Venezuela, Guyana, Suriname, and surrounding regions)
- Tree Size: 100–150 ft tall, 3–5 ft trunk diameter
- Average Dried Weight: 68 lbs/ft³ (1,090 kg/m³)
- Janka Hardness: 3,190 lbf
- Color: Dark reddish brown to purplish brown, sometimes with lighter streaks
- Grain: Straight to interlocked
- Texture: Fine to medium
Identification Characteristics
Massaranduba is identified by its deep reddish-brown heartwood, fine texture, and exceptionally high weight. The grain is usually straight but may show interlock in some boards. Freshly milled material often appears brighter and darkens over time.
Sapwood is pale and clearly distinct from the heartwood.
Key identification traits include:
- Deep reddish-brown heartwood
- Fine, even pore structure
- Straight to interlocked grain
- Very high density and weight
Working Properties
Massaranduba is difficult to work due to its density but performs well when proper techniques are used.
- Requires sharp carbide tooling
- Pre-drilling recommended for fasteners
- Machines cleanly with proper feed rates
- Sands slowly but evenly
- Excellent dimensional stability
Its hardness makes machining demanding, but finished components are extremely durable.
Safety Note
Dust from Massaranduba may cause skin or respiratory irritation in some individuals. Proper dust collection, eye protection, and respiratory protection are recommended during machining and sanding.
Common Uses
Massaranduba is commonly used in demanding applications, including:
- Exterior decking
- Heavy-duty flooring
- Structural beams and posts
- Bridges and boardwalks
- Marine and waterfront structures
Its durability makes it well suited for long-term exterior use.
Sustainability & Notes
Massaranduba is not currently listed under CITES restrictions and remains commercially available. However, responsible sourcing is important due to its use in large-scale construction.
Buyers should seek suppliers that provide documentation of legal harvesting and sustainable forestry practices.

Collector Notes
Massaranduba is less commonly collected for fine woodworking due to its extreme hardness, but it is appreciated by collectors for its stability and longevity. Straight-grained, defect-free boards are preferred for structural or accent uses.
Well-seasoned Massaranduba is exceptionally stable. Older stock that has fully acclimated often machines more predictably than freshly milled material. Proper storage helps prevent surface checking and preserves long-term usability.
