Green Ash (F. americana pictured)

Common Name(s): Green Ash

Scientific Name: Fraxinus pennsylvanica

Distribution: Eastern and Central North America

Tree Size: 50-65 ft (15-20 m) tall, 1-2 ft (.3-.6 m) trunk diameter

Average Dried Weight: 42 lbs/ft³ (680 kg/m³)

Basic Specific Gravity: .53

Hardness: 1,200 lb_f (5,340 N)

Bending Strength: 14,100 lb_f/in² (97,200 kPa)

Elasticity: 1,660,000 lb_f/in² (11,400 MPa)

Shrinkage: Radial: 4.6%, Tangential: 7.1%, Volumetric: 12.5%, T/R Ratio: 1.5

Color/Appearance: The heartwood is a light brown color, though darker shades can also be seen, which is sometimes sold as “olive ash.” Green Ash tends to be a bit darker in color than the White Ash (Fraxinus americana) pictured above.

Grain/Pore: Has a medium to coarse texture similar to oak. The grain is almost always straight and regular, though sometimes curly or figured boards can be found.

Durability: Heartwood is rated as perishable, or only slightly durable in regard to decay. Ash is also not resistant to insect attack.

Workability: Easy to work, and takes glues, stains, and finishes well.

Smell: Gives off a distinct, moderately unpleasant smell when being worked.

Safety: Ash in the Fraxinus genus has been reported to occasionally cause a decrease in lung function. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Price Range: Ash is among the least expensive utility hardwoods available domestically; it should compare similarly to oak in terms of price.

Comments: Green Ash is one of a handful of species in the Fraxinus genus that are used as commercial lumber. It has strength/mechanical properties that are very close to the related White Ash (Fraxinus americana) and is frequently mixed and sold as “White Ash.”

Some common uses for ash include flooring, millwork, boxes/crates, baseball bats, and other turned objects such as tool handles.
