American Black Walnut Wood is a North American species used for interiors such as furniture, flooring, gun stock blanks, and other wood products. Walnut has a warm, rich chocolate brown color with hints of dark purple.
This wood can be steamed or left unsteamed and generally has a straight grain. Walnut can be easily worked with hand and machine tools, painted and stained, and polished for an exceptional finish.
