Product Description
BLACK WALNUT – Juglans Nigra

American Black Walnut is a medium to large hardwood, native to the eastern regions of North America. There are two different components to walnut wood. The outer layer is called sapwood and the inner layer is called the heartwood. Walnut sapwood has a creamy white colour. The walnut heartwood colour ranges from a golden or light brown to dark chocolate brown colour, and sometimes with narrow streaks of a darker purplish-brown.

Physical & Mechanical Properties :
Walnut is hard and tough wood with medium density, has medium bending and speed and low rigidity. This wood
has a classification of good steamer bending.

Workability :
Walnuts are easy to do with manual or machine tools and can be nailed, screwed and glued properly. This wood can hold paint and color very well and can be polished with extraordinary finish. If the wood is slowly dried it has the best performance, thereby reducing the chance of quality degradation.

To cap it off, the wood also has good dimensional stability, shock resistance, and strength properties.
