Strong and moderately durable, American black walnut is very fashionable for use in furniture, cabinet making, architectural interiors and high class joinery. Walnut is a tough, hard timber of medium density, with moderate bending and crushing strengths and low stiffness. It has a good steam bending classification. It has a creamy white sapwood, while the heartwood is light brown to dark chocolate brown, occasionally with a purplish cast and darker streaks. The wood is generally straight grained, but sometimes with a wavy or curly grain.
