Distribution
Eastern USA, principally the Northern and Lake States.
General description
The sapwood of basswood is usually quite large and creamy white
in colour, merging into the heartwood which is pale to reddish brown,
sometimes with darker streaks. The wood has a fine uniform texture
and indistinct grain that is straight.
Working properties
Basswood machines well and is easy to work with hand tools making
it a premier carving wood. It nails, screws, and glues fairly well
and can be sanded, stained, and polished to a good smooth finish.
It dries fairly rapidly with little distortion or degrade. It has
a fairly large shrinkage but good dimensional stability when dry.

Physical properties
The wood is light and soft with generally low strength properties
and a poor steam bending classification.
Specific Gravity: 0.37 (12% M.C.)
Average Weight: 417 kg/m3 (12% M.C.)
Average Volumetric Shrinkage: 12.6% (Green to 6% M.C.)
Modulus of Elasticity: 10,067 MPa
Hardness: 1824 N
Durability
Non-resistant to heartwood decay, sapwood liable to attack by common
furniture beetle. The wood is permeable for preservation treatment.
Availability
USA: Reasonable availability both for lumber and veneer, particularly
from the Northern States.
Export: Available in a full range of thicknesses and specifications,
although volumes can be limited, this may change as demand increases.
