American willow (Salix spp.)
Other names: Black willow, swamp willow
Distribution
Eastern USA. Principal commercial areas are the Middle and Southern
States, along the Mississippi river.General description
The sapwood of willow varies in width according to growing conditions
and is light creamy brown in colour. In contrast the heartwood is
pale reddish brown to greyish brown. The wood has a fine even texture
and although generally straight grained it can sometimes be interlocked,
or display figure.Working properties
Willow works fairly easily with hand and machine tools but care
is needed to avoid a fuzzy surface when interlocked grain is present.
The wood nails and screws well, glues excellently, and can be sanded
and polished to a very good finish. It dries fairly rapidly with
minimal degrade although may be susceptible to moisture pockets.
Dimensional stability is good when dry.
Physical properties
The wood is weak in bending, compression, shock resistance and
stiffness, with a poor steam bending classification.Specific Gravity: 0.39 (12% M.C.) Average Weight: 417 kg/m3 (12% M.C.) Average Volumetric Shrinkage: 11.5% (Green to 6% M.C.) Modulus of Elasticity: 6960 MPa Hardness: N/A * Values for Salix nigra Durability
Non-resistant to hardwood decay. The heartwood is resistant to
preservative treatment and the sapwood is permeable.Availability
USA:Reasonable availability on a regional basis, as lumber and
veneer.Export: Very limited indeed due to low demand. Main uses
Furniture, joinery, interior mouldings, panelling, doors, sports
equipment, kitchen utensils and toys. |
