Titanium Alloy Spring Material Data
| Grade | Common designation | Density | Typical tensile strength | Typical yield strength | Elastic modulus |
|---|---|---|---|---|---|
| TC4 | Ti-6Al-4V / Grade 5 | 4.43 g/cm3 | 895-1100 MPa | 825-1000 MPa | 110-114 GPa |
| TC6 | Ti-6Al-2.5Mo-1.5Cr-0.5Fe-0.3Si | about 4.55 g/cm3 | 980-1180 MPa | 880-1050 MPa | 110-120 GPa |
Values are typical datasheet ranges. Final spring rating should be based on certified mill data, heat treatment and fatigue validation.
Titanium Alloy Selection Notes
| Grade | Best fit | Main advantage | Design caution |
|---|---|---|---|
| TC4 / Ti-6Al-4V | Lightweight corrosion-resistant components | High specific strength and broad availability | Lower modulus than steel changes load-deflection behavior |
| TC6 | Higher strength titanium spring components | Better strength margin after suitable heat treatment | Requires tighter review of heat treatment, fatigue and sourcing route |
Titanium alloy disc spring sourcing notes
Ti-6Al-4V Belleville washer, TC4 disc spring and titanium alloy spring component RFQs usually need lower weight, corrosion resistance or non-magnetic behavior rather than a direct steel replacement.
Useful RFQ inputs include target load, working deflection, installation envelope, weight limit, temperature, corrosion media, magnetic requirement, fatigue cycle and whether TC4 or TC6 is preferred.
Because titanium has a lower elastic modulus than steel, the geometry and stack layout should be recalculated before a standard spring drawing is reused. For Ti 64 springs, send the load target, available height, weight limit and whether the part must remain non-magnetic.

Common Product Questions
When should titanium alloy disc springs be considered?
They are useful when weight reduction, corrosion resistance or non-magnetic behavior matters enough to justify lower modulus and higher material cost compared with steels.
Can TC4 replace spring steel directly?
Usually not as a drop-in substitution. Titanium has a lower elastic modulus, so the spring geometry and stack design should be recalculated around the target load and travel.
Are Ti 64 springs the same review path as TC4 / Ti-6Al-4V?
In most sourcing discussions, Ti 64, Ti-64, Grade 5 and TC4 point to the same Ti-6Al-4V titanium alloy family. The practical review is whether the part should be a Belleville washer, disc spring stack or custom titanium elastic component.
