Physical & Mechanical Properties
Cottonwood is relatively light in weight. The wood is soft, and weak in bending and compression, and low in shock resistance. It has no odour or taste when dry
General machinability is fair, although tension wood is frequently present and can cause a fuzzy surface when cut, if machine blades are not very sharp or set at correct angles, which in turn will require additional care when finishing. The wood glues well and has good resistance to splitting when nailing and screwing. It dries easily but may still have a tendency to warp, with small movement in performance.
