The introduction and application of titanium spring

May 16, 2017

The titanium spring mainly has tensile titanium spring, titanium compression spring, torsion titanium spring and titanium bending spring, etc. the titanium spring has high elasticity, high strength and high plasticity, and has good fatigue resistance compared with steel spring. Titanium alloy is a kind of ideal spring material because of its high specific strength and low elastic modulus. Because of these characteristics, the titanium spring can be designed to be smaller in diameter and less in number than the steel spring in practical application. Many kinds of spring in spring, titanium is just one small part, because of its light weight, high strength, strong corrosion resistance and other characteristics, so the titanium spring is widely used in chemical engineering, marine engineering, automobile manufacturing and other fields. There are many kinds of titanium springs: tensile titanium springs, titanium shells and torsion titanium springs. Method for manufacturing titanium spring can be divided into cold roll and hot roll method. The main material is titanium spring with titanium alloy wire, titanium wire diameter less than 8mm by cold rolling method, more than 8mm with hot roll method, heat treatment of titanium spring for annealing and pickling according to customer requirements.

 

Titanium alloy is a kind of ideal spring material because of its high specific strength and low elastic modulus. High strength is the most important performance requirement for materials. Alloy is the best choice for making springs. Application of titanium spring market is not mature at present, mainly the fatigue resistance of titanium spring, no 60Si2Mn, titanium spring materials are now the main domestic manufacturers is to replace Ti-6Al-4vl, but it is not ideal material for making titanium spring, the United States has a technology company tests of a new titanium alloy material the improved titanium alloy existing formula, developed a new type of titanium alloy Ti-4.5Fe-6.8Mo-1.5Al, named it LCB, after a long test of LEB titanium alloy spring, in addition to the steel spring can reach the targets, the corrosion resistance property of titanium alloy is the most important, in the standard salt spray corrosion fatigue in the experiment, the fatigue life of steel spring, generally 50% lower than the air, and the fatigue life of titanium material LEB test than air dropped 4%. There are titanium alloy spring light weight and other characteristics, titanium has light weight, high strength characteristics, the specific gravity is only 1/2 of steel. With the popularity of titanium materials, titanium products are more and more popular. Titanium springs have high elasticity, high strength, high plasticity, and compared with steel springs, they have better fatigue resistance. Titanium in the automotive field, will greatly reduce the weight of the car, save fuel consumption, improve vehicle efficiency, reduce exhaust emissions.

Titanium alloy is a kind of ideal spring material because of its high specific strength and low elastic modulus. Compared with steel spring, the titanium spring has the advantages of light weight, small volume and high resonance frequency. Its density and elastic modulus are only half of that of steel spring, but its strength is almost the same as that of steel spring. Because of these characteristics, the titanium spring can be designed to be smaller in diameter and less in number than the steel spring in practical application. Many kinds of spring in spring, titanium is just one small part, because of its light weight, high strength, strong corrosion resistance and other characteristics, so the titanium spring is widely used in chemical engineering, marine engineering, automobile manufacturing and other fields.

Titanium alloy is a kind of ideal spring material because of its high specific strength and low elastic modulus. 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 alloys are the best choice for making springs. Application of titanium spring market is not mature at present, mainly the fatigue resistance of titanium spring, no 60Si2Mn, titanium spring materials are now the main domestic manufacturers is to replace Ti-6Al-4vl, but it is not ideal material for making titanium spring, the United States has a technology company tests of a new titanium alloy material the improved titanium alloy existing formula, developed a new type of titanium alloy Ti-4.5Fe-6.8Mo-1.5Al, named it LCB, after a long test of LEB titanium alloy spring, in addition to the steel spring can reach the targets, the corrosion resistance property of titanium alloy is the most important, in the standard salt spray corrosion fatigue in the experiment, the fatigue life of steel spring, generally 50% lower than the air, and the fatigue life of titanium material LEB test than air dropped 4%.
