Walnut Wood Lumber – Walnut is a family of wood with various grain and color variations, but generally similar properties. In the USA, Black Walnut is most often used, its heartwood ranging from a light pale brown to a dark chocolate brown with darker brown streaks. Its color can sometimes have a grey, purple, or reddish cast. The sapwood is pale yellow-gray to nearly white. Figured grain patterns such as curl, crotch, and burl are also found. Its working characteristics coupled with a rich brown coloration puts the wood in a class by itself among hardwoods. Black Walnut is rated as very durable in terms of decay resistance but is susceptible to insect attack.

Workability: Walnut Wood Lumber is easy to work provided the grain is straight and regular. Planer tear-out can sometimes be a problem when surfacing pieces with irregular or figured grain. Walnut glues, stains, and finishes well, though walnut is rarely stained. It responds well to steam bending.
