Introduction to Nickel-Titanium Alloy Gaskets
Nickel-titanium alloy gaskets are functional gaskets made of nickel-titanium shape memory alloy (Nitinol, Ni-Ti alloy), featuring unique shape memory effect (SME) and superelasticity (pseudo-elasticity), and are widely used in aerospace, medical devices, electronic equipment and other fields.
2. Material properties of nickel-titanium alloy gaskets
-Shape memory effect: It can restore the pre-set shape at a specific temperature and is suitable for occasions that require automatic adjustment or sealing.Super elasticity: The -----elastic strain range can reach over 8%, which is much higher than that of common metals (such as steel at 0.2%), and it has excellent fatigue resistance.
-Corrosion resistance: Resistant to acid, alkali and body fluid corrosion, suitable for biomedical environments.
-Temperature sensitivity: Performance varies with temperature. The phase transition temperature can be set by adjusting the composition ratio (such as nickel-titanium ratio).
3. The product advantages of nickel-titanium alloy gaskets
-Adaptive sealing: Automatically adjusts the shape when the temperature changes to enhance the sealing performance.
-Long fatigue resistance life: Suitable for dynamic load scenarios (such as equipment that starts and stops repeatedly).
-Lightweight: With a density of approximately 6.45g /cm³, it is lighter than steel but has a strength close to that of steel.
4. Application fields
-Medical devices: cardiac stents, orthopedic spacers, dental orthodontic devices, etc., taking advantage of their biocompatibility and shape memory functions.
-Aerospace: Used for pipe sealing, joint fastening, and adapting to extreme temperature changes.
-Industrial equipment: Shock absorption and sealing gaskets for high-precision instruments, such as oil valves and electronic connectors.
-Automotive industry: Thermal seals for engines or transmission systems.
5. Processing and precautions
-Processing difficulty: Nickel-titanium alloy gaskets has high hardness and is easy to work harden, requiring laser cutting or electrical discharge machining.
-Heat treatment process: Precise control is required to maintain shape memory performance.
-High cost: The cost of raw materials and processing is higher than that of ordinary metal gaskets.
- Quality Certification: All products have passed the ISO9001:2015 product quality system.
- Testing standard: Complies with ISO 10993 or ASTM F2063 standards.
- Warranty period: If there are any production quality issues after receiving the product, you can contact us at any time for handling.
- After-sales support: We offer 24-hour online customer service consultation and technical support, and respond promptly to customers' questions and demands.

FAQ
Q: Why do nickel-titanium alloy gaskets have shape memory function?
A: At a specific temperature (phase transformation temperature), nickel-titanium alloys undergo martensitic and austenitic phase transformation, enabling them to "remember" their original shape and recover after heating, thereby achieving automatic deformation or sealing.
Q: Is this gasket suitable for high-temperature environments?
A: The working temperature of conventional nickel-titanium alloys is usually ≤100℃.
Q: Are nickel-titanium gaskets for medical use safe?
A: Medical-grade nickel-titanium alloys (such as Nitinol SE508) have passed biocompatibility certification (such as ISO 10993), are resistant to body fluid corrosion, and are widely used in imimplant devices, but it is necessary to ensure surface polishing and no nickel ion release.
Q: How to choose between the superelasticity and shape memory effect of gaskets?
A: Superelasticity is suitable for scenarios that require repeated deformation (such as shock absorption), and shape memory effect is applicable to one-time deformation triggered by temperature (such as heat-activated sealing).
Q: Why are nickel-titanium gaskets more expensive than ordinary metal gaskets?
A: The cost of raw materials is high (nickel and titanium are expensive), and the processing requires specialized equipment (such as laser cutting and precision heat treatment), significantly increasing the complexity of the process.
