Eastern Cottonwood wood properties

Also known as: cottonwood, eastern poplar.

Type hardwood
Botanical name Populus deltoides
Modulus of elasticity (MOE) 1,370,000 psi
Specific gravity 0.45
Density (approx) 28 lb/ft³ (2.3 lb per board foot)
Janka hardness 430 lbf
Shrinkage (tangential / radial) 9.2% / 3.9%
Region Central and eastern United States

A 1 in x 6 in x 8 ft board of Eastern Cottonwood weighs about 9.4 lb (roughly 28 lb per cubic foot). Its Janka hardness of 430 lbf is harder than about 9% of the woods in our database.

Uses and working notes

Common uses: boxes, crates, veneer, plywood, utility lumber.

Durability: Non-durable, and an easy target for boring insects.

Workability: Easy to cut, but keen blades prevent fuzz; grips nails weakly, warps while drying; finishes and glues well.

How these numbers were sourced

MOE, SG (12% MC), Janka and shrinkage from The Wood Database (cites USDA FPL Wood Handbook). Uses, region, durability and workability summarized from The Wood Database. Eastern Cottonwood is not listed in the FPL/Hoadley dimensional change coefficient table (Popular Woodworking reproduction), so CT/CR are omitted. Price indicative.
