Other names:Peacock wood, yellow elm
Distribution area:The United States east.

Distribution
Eastern USA.

General description
Hackberry is closely related to sugarberry (Celtis laevigata) and is a member of the elm family. There is little difference between sapwood and heartwood which is yellowish grey to light brown with yellow streaks. The wood is very susceptible to blue staining before and after kilning and has irregular grain, occasionally straight and sometimes interlocked, with a fine uniform texture.

Working properties
The wood planes and turns well and is intermediate in its ability to hold nails and screws, and stains and polishes satisfactorily. Hackberry dries readily with minimal degrade. It has a fairly high shrinkage and may be susceptible to movement in performance.
Physical properties
Hackberry is moderately hard, heavy and has medium bending strength, high shock resistance but is low in stiffness. It has a good steam bending classification.

Specific Gravity: 0.53 (12% M.C.)
Average Weight: 593 kg/m3 (12% M.C.)
Average Volumetric Shrinkage: 13.5% (Green to 6% M.C.)
Modulus of Elasticity: 8205 MPa
Hardness: 3914 N

Durability
Non-resistant to heartwood decay. Liable to attack by forest longhorn and Buprestid beetle. The heartwood is moderately resistant to preservative treatment but the sapwood is permeable.

Availability
USA: Reasonable in lumber but mainly in the thinner standard thicknesses, and lower grades.
Export: Limited due to low demand, and concerns about internal staining.

Main uses
Furniture and kitchen cabinets, joinery, doors and mouldings.
