Nickel-titanium gaskets are revolutionizing traditional material applications through their unique properties

Nickel-titanium memory alloy (Nitinol) gaskets have demonstrated significant advantages in multiple fields, such as aerospace, medical, automotive, and electronic, due to their unique shape memory effect and super elasticity. The following are its core advantages and related news updates:

The advantages of nickel-titanium memory alloy gaskets
Shape memory effect

It can restore the preset shape at a specific temperature, is suitable for high-temperature environments (such as spacecraft seals), can automatically adapt to deformation, and improve the reliability of sealing.

Superelasticity (pseudo-elasticity)

It can withstand significant deformation without permanent damage and is suitable for scenarios with frequent vibration (such as automotive engine gaskets), reducing fatigue failure.

Corrosion resistance

Superior to traditional stainless steel, it is suitable for long-term use in fluid environments (medical implants) or corrosive industrial environments.

Lightweight and high strength

Lighter than steel but with similar strength, it is suitable for weight reduction requirements in aerospace.

Biocompatibility

It is used in the medical field for orthopedic or cardiovascular implants to reduce rejection reactions.

Breakthroughs in the medical field

Research and development of degradable nickel-titanium alloys (2024) : Chinese scientists published a paper in Nature Materials to develop nickel-titanium alloys that can be degraded in vivo for use in temporary bone fixation pads to avoid secondary surgeries.

Innovation in the automotive industry

Tesla Battery Pack Sealing (2023) : Nickel-titanium gaskets are used to address leakage issues caused by battery thermal expansion, enhancing the safety of electric vehicles.

Toyota shock absorption components: Patents show that it uses memory alloy for engine mounting gaskets to reduce vibration noise (2024).

Miniaturization of electronic devices

Apple Patent (2024) : Exploring nickel-titanium alloy gaskets for foldable phone hinges to enhance durability.

Upgrading of industrial equipment
