Poisson’s Ratio Values for Titanium Alloys

Poisson’s ratio is a material property that describes the ratio of lateral strain to longitudinal strain. For titanium alloys, the Poisson’s ratio typically ranges from 0.32 to 0.37. The following table provides a curated list of Poisson’s ratio values for common titanium alloys.

Unless stated otherwise, all values are taken at standard room temperature (approximately 20°C or 68°F).
