Black Ash is one of a handful of species in the Fraxinus genus that are used as commercial lumber. It’s not quite as strong or dense as the related White Ash (Fraxinus americana); this is most likely due to its slower growth rate, which causes a higher proportion of weaker earlywood sections. The closer ring spacing can also be used to distinguish Black Ash from White Ash.
The heartwood is a light to medium brown color. Sapwood can be very wide, and tends to be a beige or light brown; not always clearly or sharply demarcated from heartwood. Black Ash tends to be a bit darker in color than White Ash.
Has a medium to coarse texture similar to oak. The grain is almost always straight and regular, though sometimes curly or figured boards can be found.
