Titanium alloy spring has the advantages of small size, light weight, excellent corrosion resistance and fatigue resistance. Because the shear modulus of the titanium alloy material is larger than that of the steel, the number of turns required to bend is less than that of the steel spring. Even if the specific gravity of the two materials is the same, because the titanium alloy spring uses less material, the weight is lighter than the steel spring. In most cases, the weight of the titanium alloy spring is 60% to 70% lighter than the steel spring, and the height design of the titanium alloy spring can also be reduced, which is 50% to 80% lower than the steel spring.

Another advantage of titanium springs is corrosion resistance. In the standard salt spray corrosion fatigue test, the fatigue life of the general steel spring is reduced by 50% compared with that in the air. In the same test, the fatigue life of the titanium spring decreased by only 4% compared to the air. Moreover, unlike steel springs, titanium springs do not require protective coatings.

Spring is a relatively special part, it is widely used in various fields of national production and life, such as cars, motorcycles, bicycles and other vehicles, computers, clocks, light switches, toys, clamps and other daily necessities are used to spring, mainly play a role in shock absorption, energy storage.

In recent years, titanium alloy has become a new choice of spring materials because of its high specific strength, low elastic modulus and good corrosion resistance. Compared with steel springs, titanium springs have the advantages of light weight, small volume and high resonance frequency, and their density and elastic modulus are only half of that of steel springs, while their strength is almost the same as that of steel springs. Due to these advantages, titanium springs can be designed to be smaller in diameter, fewer turns and greatly reduced in weight than steel springs in practical applications.

As far as springs are concerned, high strength is the most important performance requirement for materials, so high-strength β titanium alloys, such as Ti-3Al-8V-6Cr-4Mo-4Zr and Timetal LCB (Ti-6.8Mo-4.5Fe-1.5Al) alloys are the best materials for manufacturing springs.
