  • White ash Fraxinus americana

The timber

Black ash
The timber is greyish-brown to brown in colour, darker than that of white ash, (F. americana) and inferior to that timber in general strength properties and lighter in weight, about 560 kg/m³ when dried. A certain amount of this species is used for interior trim and fittings It takes a good finish.

Green ash
Produces timber similar to American white ash in appearance, but inferior to that timber in hardness, strength and toughness. It weighs about the same as white ash, about 670 kg/m³ when dried and is used for similar purposes as white ash, except for striking tool handles.

White ash
The sapwood is almost white in colour and the heartwood varies from light brown to reddish-brown rather similar to European ash. but a little lighter in weight, about 670 kg/m³ when dried.
