Common Name(s): Black walnut, American walnut
Scientific Name: Juglans nigra
Distribution: Eastern United States
Tree Size: 100-120 ft (30-37 m) tall, 2-3 ft (.6-1 m) trunk diameter
Average Dried Weight: 610 kg/m3 (MC 12%)
Shrinkage: Radial: 5.5%, Tangential: 7.8%, Volumetric: 12.8%, T/R Ratio: 1.4
Color/Appearance: Heartwood can range from a lighter pale brown to a dark chocolate brown with darker brown streaks. Color can sometimes have a grey, purple, or reddish cast. Sapwood is pale yellow-gray to nearly white. Figured grain patterns such as curl, crotch, and burl are also seen.
Grain/Texture: Grain is usually straight, but can be irregular. Has a medium texture and moderate natural luster.
Rot Resistance: Black walnut is rated as very durable in terms of decay resistance, though it is susceptible to insect attack.
Workability: Typically easy to work provided the grain is straight and regular. Planer tearout can sometimes be a problem when surfacing pieces with irregular or figured grain. Glues, stains, and finishes well (though walnut is rarely stained). Responds well to steam bending.
Odor: Black walnut has a faint, mild odor when being worked. This odor is common among most Juglans species (except butternut) and can be used to separate it from other unrelated walnut lookalikes.
Allergies/Toxicity: Although severe reactions are quite uncommon, black walnut has been reported as a sensitizer. Usually most common reactions simply include eye and skin irritation. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.
Pricing/Availability: Very popular and widely available, though board widths can sometimes be narrow. Wastage can be high if sapwood is not accounted for in projects. Considered a premium domestic hardwood, prices are in the high range for a domestic species.
Sustainability: This wood species is not listed in the CITES Appendices, and is reported by the IUCN as being a species of least concern.
Common Uses: Furniture, cabinetry, gunstocks, interior paneling, veneer, turned items, and other small wooden objects and novelties.
Comments: It would be hard to overstate black walnut’s popularity among woodworkers in the United States. Its good working characteristics, coupled with its rich brown coloration puts the wood in a class by itself among temperate-zone hardwoods. To cap it off, the wood also has good dimensional stability, shock resistance, and strength properties. In limited situations, black walnut can sometimes be considered as an alternative to ebony and other dark colored hardwoods.
