American White Oak Wood
Categories:	Wood and Natural Products; Wood; Hardwood
Material Notes:	Due to acidic nature, may stain when in contact with iron under damp conditions. May also corrode metals. Ring-Porous Hardwood. Least easy to work with hand tools. Excellent steam bending, excellent planing, fair shaping. Data is based on small, clear, air-dried samples unless specified. Usual surface texture: Medium Dimensional changes when dried lumber is subjected to variations in humidity during service: Medium Resistance to fungal decay (Heartwood in ground contact): Durable (15 to 25 years) Resistance to penetration by preservatives: Extremely resistant Common Applications: Furniture, cabinet work. Tight cooperage Property values marked by an asterisk (*) have been taken from an unusually old reference source.
Key Words:	Quercus alba; Q.spp.; Lumber, Timber
