Red alder is almost white when freshly cut but quickly changes on exposure to air to 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 and polishing. It nails, screws and glues well, and can be sanded, painted, or stained to a good finish. It dries easily with little degrade and has good dimensional stability after drying.
