- Janka hardness
- 960 lbf
- Specific gravity
- 0.6
- Workability
- Good when grain is straight; irregular grain risks tearout
Peruvian walnut shares a genus with American black walnut (Juglans) and a South American zip code, with deep chocolate-brown heartwood that's typically more uniform than domestic walnut's — sometimes with lighter streaks that turn into waste at the milling stage.
Working Properties
Peruvian walnut machines readily as long as the grain stays straight and cooperative; irregular or figured sections invite planer tearout the moment you get comfortable. It glues, stains, and finishes well. It's noticeably softer than American black walnut (roughly 960 lbf vs. 1,010 lbf) and less patient with UV — its color shifts with light and moisture more readily than domestic walnut's does.
Typical Uses
Furniture, cabinetry, gunstocks, and veneer, generally as a less expensive substitute for American black walnut.
