Origin
Central and South America (from Mexico down to southern Brazil)
Janka Hardness
2,520 lbf
Average Weight
4.7 lbs/bf
Color
Freshly cut heartwood is dull grayish-purple, deepening to a rich eggplant purple within days of exposure; color gradually shifts to dark brown with a purple hue over time with UV exposure; a UV-inhibiting finish is recommended to slow color change.
Working Characteristics
- Moderate dulling effect on cutters
- overheating from dull tools or excessive cutter speeds causes resin exudation that can clog tools — sharp tools and controlled speeds essential
- tearout possible depending on grain orientation.
