(Red Alder, Western Red Alder)

Scientific Name: Alnus rubra

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.
