Disclosed is a beta-titanium alloy consisting of, in weight percent, 5-15% of V, 0.5-2.5% of Fe, 0.5-6% of Mo, 0.5-5% of Cr, 1.5-5% of Al, and the balance of Ti and impurities. When the weight % of V content is expressed as X<SUB>V</SUB>, the weight % of Fe content is expressed as X<SUB>Fe</SUB>, the weight % of Mo content is expressed as X<SUB>Mo</SUB>, and the weight % of Cr content is expressed as X<SUB>Cr</SUB>; the value of X<SUB>V</SUB>+2.95X<SUB>Fe</SUB>+1.5X<SUB>Mo</SUB>+1.65 X<SUB>Cr </SUB>is 15-23%. Such a beta-titanium alloy has excellent cold workability, while having higher strength than Ti-20V-4Al-1Sn beta-titanium alloy.
