Bidirectional nickel titanium alloy spring

Shape memory: Automatically restores the preset shape when the temperature changes, enabling two-way action (heating stretching/cooling shrinking).

Superelasticity: resistant to large deformation, can withstand high strain without permanent deformation.

Long life: Performance is maintained after millions of repetitions.

Lightweight: Lighter than traditional metal springs.

1.Temperature drive: heat extension, cooling contraction, automatic bidirectional deformation.

2.Superelasticity: can withstand large deformation after full recovery, strong fatigue resistance.

3.High precision control: stable shape variable and recovery force, good repeatability.

4.Corrosion resistance: suitable for body fluids, moisture and other environments (such as medical field).

5.Lightweight: lighter than steel springs, but similar in strength.

Typical applications: medical devices (such as catheters), smart homes, aerospace actuators, etc.

1. Medical equipment: surgical robot, endoscope, orthopedic arch wire, etc.

2. Smart home: temperature control valves, automatic opening and closing devices (such as smart Windows, faucets).

3. Automotive industry: engine temperature control components, shock absorption system (high temperature resistance, fatigue resistance).

4. Consumer electronics: mobile phone camera module, folding screen hinge (super elastic buffer).

Q1: What is the difference between bidirectional nickel-titanium spring and ordinary spring?
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).
