PURPOSE: A beta titanium alloy with low elasticity coefficient is provided to offer an excellent mechanical property by adding tantalum(Ta), hafnium(Hf), molybdenum(Mo), and tin(Sn). CONSTITUTION: A beta titanium alloy having low elasticity coefficient includes Nb 37~41 weight %, Zr 5~8 weight%, rest titanium, and impurity. The coefficient of elasticity of the beta titanium alloy is less than 55 Gpa. One or two elements of tantalum(Ta), hafnium(Hf), molybdenum(Mo), and tin(Sn) are added in 3 weight % less.
