Introduction and application of titanium and titanium alloy springs

Titanium springs mainly include tensile titanium springs, titanium compression springs, torsion titanium springs and titanium bending springs. Titanium springs have high elasticity, high strength, and high plasticity, and have better fatigue resistance than steel springs. Titanium alloy has high specific strength and low elastic modulus, so it is an ideal spring material. Compared with steel springs, titanium springs have the advantages of light weight, small size and high resonant frequency. Its density and elastic modulus are only half of steel springs, and the strength is almost the same as steel springs. Due to these characteristics, the titanium spring can be designed to have a smaller diameter and fewer turns than a steel spring in practical applications. There are many types of springs, and titanium springs are only a small part of them. Because titanium has the characteristics of light weight, high specific strength, and strong corrosion resistance, titanium springs are widely used in chemical, marine engineering, automobile manufacturing and other fields. There are many types of titanium springs: tensile titanium springs, titanium compression springs, torsion titanium springs and so on. The manufacturing methods of titanium springs are roughly divided into cold-rolling methods and hot-rolling methods. The main material of titanium spring is titanium alloy wire. The diameter of titanium wire is generally less than 8mm by cold coil method, and the diameter of titanium wire is greater than 8mm by hot coil method. The heat treatment of titanium spring can be annealed and pickled according to customer requirements.

 

Titanium alloy has high specific strength and low elastic modulus, so it is an ideal spring material. High strength is the most important performance requirement for materials, so high-strength beta titanium alloys such as Ti-3Al-8V-6Cr-4Mo-4Zr and Timetal LCB (Ti-6.8Mo-4.5Fe-1.5Al) alloys are used to make springs The best choice. The application market of titanium springs is not yet mature, mainly due to the fatigue resistance of titanium springs, which is not as strong as 60Si2Mn. The titanium spring materials used by domestic manufacturers are mainly replaced by Ti-6Al-4vl, but it is not for making titanium springs. Ideal material. A technology company in the United States experimented with a new titanium alloy material, improved the existing titanium alloy formula, and developed a new type of titanium alloy material Ti-4.5Fe-6.8Mo-1.5Al, which was named LCB, after long-term use and testing of LEB titanium alloy springs, in addition to reaching the indicators that steel springs can achieve, the most important thing is the corrosion resistance of titanium alloys. In the standard salt spray corrosion fatigue test, the general steel spring fatigue life It is 50% lower than air, and the fatigue life tested with titanium LEB material is 4% lower than air. There is also light weight and other characteristics of titanium alloy springs. Titanium has the characteristics of light weight and high specific strength, and its specific gravity is only 1/2 of that of steel. With the popularization of titanium materials, titanium products are becoming more and more popular among people. Titanium springs have high elasticity, high strength, and high plasticity. Compared with steel springs, they have better fatigue resistance. The application of titanium in the automotive field will greatly reduce the weight of the car, save fuel consumption, improve the efficiency of the car, and reduce exhaust emissions.
