The old master furniture maker’s dream, American Walnut machines and finishes beautifully into flooring works of art, often with curly or wavy grain. Its heartwood ages magnificently to a rich, mellow, medium dark brown, and where present, its pale sapwood adds attractive contrast.
Its hardness is slightly more than American Black Cherry, and its relative movement in service is 25% better than Oak. Altogether, its natural beauty combined with its superior mechanical and finishing qualities make Walnut our first choice in the entire universe of American Hardwoods.
- The sapwood of black walnut is nearly white, while the heartwood is light brown to dark, chocolate brown, often with a purplish cast and darker streaks. The wood is heavy, hard, and stiff and has high shock resistance.
- Mechanical Properties:
- Janka side hardness is about 1,010 lb. for dry material. Shrinkage green to ovendry: radial 5.5%, tangential 7.8%, volumetric 12.8%.
- Working Properties:
- It is straight grained and easily worked with hand tools and by machine. It finishes beautifully and holds paint and stain exceptionally well. It also glues and polishes well.
