American Black Walnut (Juglans nigra) aka Black Walnut and Walnut, is a durable hardwood timber of medium density, with a Janka hardness value of 1010, moderate bending, low stiffness, and good dimensional stability. It is native to the United States, with its principal commercial region in the Central States. Its good working characteristics coupled with its rich brown coloration puts the wood in a class by itself among temperate-zone hardwoods. The wood is tight-grained and polishes to a very smooth finish. Prized worldwide for its deep rich color, additional staining and oiling will deepen the richness and natural characteristics of the wood.

The sapwood of American Black Walnut is creamy white while the heartwood is light to dark chocolate brown, occasionally with a purplish cast and darker streaks. The majority of the commercially produced American Black Walnut lumber is steam treated to darken the sapwood in order to reduce the contrast. The wood is generally flat-grained but can contain a curly grain that produces a decorative figure.
