Bidirectional Nitinol Torsion Sping Af 60C Mf 30C
Product introduction
nitinol torsion sping product knowledge
Made of nickel-titanium shape memory alloy (Nitinol), it features unique superelasticity and shape memory effect.
Advantages of bidirectional nitinol torsion sping (dual shape memory alloy spring) :
High elastic strain (up to over 8%)
Long service life and strong stability
Adapt to complex working conditions
Characteristics of bidirectional nitinol torsion sping:
Superelasticity: It can withstand significant deformation and return to its original shape.
Shape memory: Restore the preset shape after heating.
Fatigue-resistant, corrosion-resistant and with good biocompatibility.
Application scenario of bidirectional nickel-titanium spring:
Medical: Dental orthodontic wires, vascular stents.
Industry: Spacecraft antennas, robot drive components.
Consumer electronics: Spectacle frames, mobile phone hinges.
FAQ
Q1: What is the difference between bidirectional nitinol torsion sping?
A1: Bidirectional nickel-titanium springs can automatically expand with temperature changes (shape memory + superelasticity), ordinary springs only rely on mechanical force deformation and fatigue.
Q2: How long will it last?
A2: It can reach more than one million cycles, far more than ordinary metal springs.
Q3: What temperature environments are suitable for operation?
A3: Typical operating temperature -50℃~150℃, depending on alloy formulation (can be customized).
Q4: How to adjust its deformation temperature point?
A4: It can be achieved by adjusting the proportion of nickel-titanium alloy, which needs to be customized by the manufacturer.
Q5: How much higher is the price than ordinary springs?
A5: Initial costs are 3-10 times higher, but long life and maintenance-free reduce overall costs.
Q6: Is it in stock or must it be customized?
A6: Regular models may be available in stock, but most need to be customized according to parameters (size/temperature/strength).
