Titanium alloy with improved properties

A titanium alloy comprising, in weight %:

• aluminum from about 6.3 to 6.7;
• vanadium from about 1.5 to about 1.9;
• molybdenum from about 1.5 to about 1.9;
• silicon from about 0.34 to about 0.38;
• oxygen from about 0.18 to about 0.21;
• iron from about 0.1 to about 0.2;
• carbon from about 0.01 to about 0.05;
• and
• balance titanium with incidental impurities, wherein the alloy comprises a room temperature longitudinal low cycle fatigue (LCF) maximum stress of at least about 950 MPa over about 20,000 cycles and a room temperature transverse LCF maximum stress of at least about 970 MPa over about 25,000 cycles.
