Pau Ferro (also known as Morado or Bolivian Rosewood)
Machaerium scleroxylon • Exotic/Tropical Hardwood
Grain Pattern
Interlocked, wavy, or irregular grain with a fine to medium texture; often displays a high degree of figure such as marbling or striping depending on the cut.
Color Description
Heartwood ranges from light tan to dark violet-brown with black streaks. Sapwood is a distinct yellowish-white. It has a high natural luster and can darken slightly or become more muted with UV exposure.
Hardness Rating
1,960 lbf (Very Hard)
Durability Rating
Durable to Very Durable; naturally resistant to decay and most insect attacks due to high density and natural oils.
Common Uses
Musical instruments (fingerboards, guitar backs/sides), high-end furniture, cabinetry, veneer, turned objects, and knife handles.
Geographic Origin
Tropical South America, primarily Brazil and Bolivia.
Market Value & Sustainability
Estimated Market Value
$20.00 to $45.00 per board foot depending on figure and thickness.
Wood Age Estimate
Indeterminate based on photo; however, the rough texture suggests a recently milled or raw reclaimed piece without polished oxidation.
Sustainability Status
Not currently CITES listed or on the IUCN Red List of Threatened Species, though it is often used as a more sustainable substitute for Rosewood (Dalbergia species).
Workability
Fairly difficult to work due to high density and interlocked grain causing tearout. High oil content can interfere with gluing. Dulls cutting edges quickly.
Notable Features
Known for a distinct, slightly medicinal scent when being worked. Can cause skin irritation or allergic reactions in sensitive individuals (sensitizer).
Finish Recommendations
Wiping with a solvent (acetone) before gluing/finishing is recommended to remove surface oils. Responds well to lacquer, carnauba wax, and natural oil finishes for a high-gloss look.
Identification Confidence
Medium-High; the distinct coloring, fine texture, and characteristic dark streaks seen in the macro grain are highly indicative of Machaerium scleroxylon.
