Description of titanium springs

1) Material: Titanium alloy

Gr5,TC4(Ti-6Al-4V)TB5 Ti15333(Ti-15V-3Cr-3Sn-3Al),TB9,Ti38644(Ti-3Al-8V-6Cr-4Mo-4Zr)Timetal LCB(Ti-6.8Mo-4.5Fe-1.5Al)TA11(Ti-8Al-1Mo-1V)

2) Standard:

DIN 2096, EN13298,UIC 822,TB/T 1025, GB/T 23934, HB8292, JIS B2704, JB/T 10416,GB/T 1239.2

 

3) Production technology and wire diameter

Cold Coiled: Diameter: ≤ 8mmHeat Coiled: Diameter: > 8mm

4) Special features of titanium springs

Low density,High specific strength,excellent corrosion resistance,Rustless.Better Anti-fatigue performance, Good heat treatment performance,Lower Elastic modulus.Higher strength-to-weight ratic,Higher Elastic Limit,Higher Fatigue limit,Higher impact toughness and  Higher resonant frequency.

5) Why we choose Titanium Springs

Because of the special features of titanium,the titanium springs can be designed with smaller diameter,less coils than the steel springs during Practical application.

From the form you can see that the titanium can reduce much more weight.

The steel springs will have to be longer and with larger diameter.

But the titanium can resolve this problem for you.

 

6) Types of titanium springs

Train springs, The high voltage switch spring, Elevator spring, Automotive suspension spring, tension spring,Compression spring,Torsion spring, Disc Spring, Vortex coil spring, Wave spring,Plate spring,etc.
