COMMON NAMES: Pau Ferro, Morado, Bolivian Rosewood, Santos Rosewood.
DESCRIPTION: Density 940 kg/m3. Colour can be highly varied, ranging from reddish/orange to a dark violet/brown, usually with contrasting darker black streaks. Narrow sapwood is a pale yellow and is clearly demarcated from the heartwood. Grain is typically straight, though sometimes slightly irregular or interlocked. Fine, even texture and a naturally high luster.
RECOMMENDATIONS: Pau Ferro is considered overall to be of fair workability, as it can blunt the cutting edges of tools, and any irregular grain has a tendency to tear out during machining operations. Also, many of the same challenges in gluing rosewoods are common to Pau Ferro as well. Pau Ferro turns and finishes well. Can cause eye and skin irritation.
DRYING: Dries slowly. No risk of deformation but it can crack.
USES: Guitar tops, backs, fingerboards , headplates and bridges. Wind instruments
