Alder
Alnus rubra
Where it Grows
Principally the Pacific Northwest, where it is the most abundant commercial
hardwood. Average height is 90 feet and the tree matures in 25 to 40 years, but
will begin to deteriorate by 60 to 80 years of age. Alder grows well on burned
over lands and thrives in areas that have been ravaged by fire, earthquakes or
logging.
Main Uses
Furniture, kitchen cabinets, doors, shutters, mouldings, panel stock, turnings,
carvings and kitchen utensils.
General Description
Red alder, a relative of birch, is almost white when freshly cut but quickly
changes on exposure to air, becoming light brown with a yellow or reddish tinge.
Heartwood is formed only in trees of advanced age and there is no visible
boundary between sap and heartwood. The wood is fairly straight-grained with a
uniform texture.
Working Properties
Red alder machines well and is excellent for turning. It nails, screws and glues
well, and can be sanded, painted, or stained to a good finish. When stained, it
blends with walnut, mahogany or cherry. It dries easily with little degrade and
has good dimensional stability after drying.
Physical Properties
Red alder is a relatively soft hardwood of medium density that has low bending
strength, shock resistance and stiffness.
