Elongation of Common Titanium Alloys
Titanium alloys are known for their good combination of strength and ductility. The elongation at break of titanium alloys typically ranges from about 10% to 25%, depending on the specific alloy composition and heat treatment.
The following table provides a comprehensive list of elongation at break values for common titanium alloys.
