Performance:

The specific gravity of the wood is about 0.64. The wood grain is rough but uniform. Wood has good dimensional stability after drying

Color:

American black walnut compares with Europe, generally the color is darker, the difference between its heartwood and white wood is more obvious than European walnut.

Feature:

The white wood of the American Black Walnut is milky white, and the heartwood is light brown to brown black, often with purple cracks and darker stripes.

Walnut is usually straight wood grain, sometimes with corrugated or curved wood grain, resulting in attractive, decorative graphics. 

Walnut is a kind of medium density tough hard wood, with moderate flexural strength and fracture strength, low rigidity and good steam bending performance.

Walnut is easy to process by hand tools and machine,excellent nailling and adhesive performance ,also with excellent paint and dye retention ability, can get a fine surface after polishing.

Walnut drying is slow and requires careful care to avoid drying aging. Walnut has good dimensional stability and with strong corrosion resistance to core wood. Its white wood will be eroded by the pollinator beetle.
