Titanium Springs

Titanium Springs: Wire Helical Compression, Torsion & Extension Springs

Titanium material has a high strength-to-weight ratio and a high resistance to corrosion, the two primary reasons engineers consider this alloy when analyzing product requirements. Because of their strict focus on high-performance applications, the aerospace manufacturing community and the performance racing component sector are the two most prevalent industries for titanium springs.

TI 3-8-6-4-4, commonly known as Beta C, is typically the titanium material of choice for spring applications and designs when weight and strength are important to control. This material is available in a solution-treated condition which allows for ease of formability and is heat treated (aged) to provide its full tensile and hardness properties after it has been formed into its configuration/shape. The weight density of this material is approximately 60% of most other common spring materials. For example, a carbon steel wire (music wire) spring that weighs 10 pounds can be substituted with titanium wire spring which will weigh approximately 6 pounds in the same configuration. This affords engineers a chance to improve the design by lowering the stress with the weight advantage that titanium provides.

Manufacturing springs and processing titanium material is more difficult than your standard spring material. Nicks, marks and deformation on most spring material do create stress risers and it is much more critical with titanium that these imperfections are not created. The skill of making titanium springs is not commonly known in the spring industry — in particular, how this material reacts in the heat treating process. It is vitally important not to contaminate titanium material while cold working and heat treating; titanium material must be cleaned chemically or mechanically prior to and after any heat treating process.

Most spring configurations can be made out of titanium wire but the material and processing costs are much higher than typical spring material. When the precise weight to strength ratio is not required titanium material is not practical to use, but in those specific applications where it is, there is no better and in most cases no other choice than Ti 3-8-6-4-4.
