Nitinol Spring
In the past, most temperature control valves employed materials like waxy or mechanical structures like bellows. However, nitinol springs (shape memory alloy springs) are widely used for modern applications because of their superior reliability.
Specific advantages of SMA springs (nitinol spring) include:
A. No gas or liquid leaks
B. 2-3x higher heat sensitivity compared to waxy components.
C. Shorter response time to temperature changes, since SMA material contacts the media directly.
D. Lowered the total cost of modern SMA springs.
We provide nitinol springs (nickel-titanium springs) with competitive prices and various specifications.
Nitinol spring (nickel-titanium spring) by round nitinol wire, with minimum 0.2mm Nitinol wire diameter, strength, and size per drawing.
Nitinol spring by flat nitinol wire, wire size, strength, and size per drawings
One-way shape memory nitinol spring
Spring that can be compressed (Nitinol Compression Coils / Nitinol Compression Spring) or stretched (Nitinol Tension Springs) at a temperature higher than the Af point. One way nitinol spring can not be recovered with temperature.
Two-way shape memory nitinol spring
Spring that can be compressed (Nitinol Compression Coils / Nitinol Compression Spring) or stretched (Nitinol Tension Springs) at a temperature higher than the Af point. Two-way nitinol spring will be recovered with temperature and can be deformed repeatedly
Two-way shape memory spring is widely used in many fields, such as aerospace, mechanical and electronic products, biomedical, building structure, daily life (Water temperature adjustment parts in bathroom & kitchen), etc.
