Hardness and Workability
Janka Hardness Rating: Approximately 1,960 lbf (8,720 N)
Pau Ferro is a dense and durable wood, making it highly resistant to wear. It machines well, though its interlocking grain can pose challenges when planing. It polishes to a smooth finish and does not require excessive grain filling.
Grain Structure and Porosity
Pau Ferro has a medium to fine texture with a straight to slightly wavy grain. It varies in color from golden brown to deep reddish-brown with contrasting streaks. Its grain is relatively closed, requiring minimal finishing preparation.
Sustainability and Ethical Considerations
Pau Ferro is not currently endangered, but sustainable sourcing is encouraged as demand increases. Many manufacturers use Pau Ferro as a responsible alternative to rosewood, ensuring compliance with international trade regulations.
Pau Ferro continues to gain popularity as a tonewood due to its balanced sound, durability, and sustainability. Its use in fingerboards and bridges makes it a strong choice for both acoustic and electric instruments.
