Nitinol Wire Heat Resistance & Specifications (Industry Standard for Independent Station)

Core definition: The material of nitinol wires heat resistant (nickel-titanium) is a shape memory and superelastic alloy; its heat resistance is classified according to specifications - not all have high heat resistance, and is strictly limited by the phase transition temperature (Af) and working temperature.

1. Core Heat Resistance Conclusion

Safe continuous working temperature: -50℃ ~ 150℃

Loss of shape memory function: ＞300℃

Material permanent damage (brittle/fracture): ＞500℃

Melting point: ~1310℃ (only structural melting temperature, no practical application value)

表格

Wire Diameter	Transformation Grade (Af)	Max Safe Working Temp	Heat Resistance Performance	Typical Industry Applications
Φ0.1mm ~ Φ0.3mm	15℃ (Low Temp)	80℃	Soft below 15℃; rigid above 15℃; not resistant to high temp	Micro-robot, precision actuator, smart wearable
Φ0.1mm ~ Φ0.3mm	40℃ / 60℃ (Normal)	120℃	Stable shape memory; mild heat resistance	Medical catheter, precision switch, smart glasses frame
Φ0.3mm ~ Φ1.0mm	80℃ (Medium Temp)	150℃	Best heat resistance in conventional grades	Industrial valve, automotive sensor, aerospace component
Φ1.0mm ~ Φ3.0mm	40℃ / 60℃ / 80℃	120℃ ~ 150℃	High strength; heat resistance consistent with grade	Mechanical connector, anti-loose structure, heavy-duty actuator
Custom Diameter	-50℃ ~ 100℃ (Custom)	80℃ ~ 150℃	Tailored heat resistance & activation temp	Medical implant, special equipment, military component

3. Independent Station Key Selling Points

Grade-defined heat resistance: Different specifications match different temperature environments, no universal type.

Ultra-fine to thick specifications complete: Φ0.1mm–Φ3.0mm in stock, support custom processing.

Shape memory + superelasticity dual performance: Stable within safe temperature range.

Clear application boundaries: Avoid misapplication in high-temperature scenes above 150℃.

4. Buyer Prompt

Nitinol wire is not high-temperature alloy; cannot be used in scenes above 300℃ for a long time.

Selection priority: Working temperature → Transformation grade → nitinol wires heat resistant Wire diameter.
