What are the key mechanical properties of European ash?

European ash (Fraxinus excelsior) has a density of 650–750 kg/m³ at 12% moisture content, characteristic bending strength of 38–50 N/mm² (strength class D40–D50), and mean modulus of elasticity of 12,000–13,000 N/mm². It has exceptional shock resistance and elasticity, making it historically the preferred timber for tool handles, sports equipment, and any application requiring impact absorption.

It has exceptional shock resistance and elasticity, making it historically the preferred timber for tool handles, sports equipment, and any application requiring impact absorption. Its hardness (Janka rating approximately 5,900 N) places it between oak and beech for wear resistance.
