Working Properties

Ash is straight grained, heavy, hard, strong, stiff, and wears smooth with high shock resistance. It machines well and is better than average in nail and screw holding capacity. It glues moderately well. Black, Green, Pumpkin, and Blue ashes have lower specific gravities and lower strength properties, but are still moderately strong, hard and stiff compared to other native hardwoods. They also split easier, shrink more, are average in workability and perform less well in service.


Classed as slightly to non-resistant to heartwood decay.
