Titanium 6-2-4-6
6Al-2Sn-4Zr-6Mo
Material Data Sheet
Alpha-beta alloy Ti 6-2-4-6 is a stronger derivative of Ti 6-2-4-2, offering higher strength, depth hardenability and elevated temperature properties up to 450°C. This alloy is similar in forgeability and crack sensitivity to Ti 6-4 but is capable of being heat-treated to higher strengths in greater section sizes than Ti 6-4 alloy.
The properties of this alloy are influenced by its thermo-mechanical history.
Enhanced strength, ductility, and low-cycle fatigue properties are the signatures of alpha-beta forged material.
