Nitinol Washers Applications

  • Power Industry
    Nitinol gaskets have a self-pressurization function, which can significantly reduce the contact resistance of power joints and reduce joint heating, thus reducing power transmission and transformation energy consumption and improving the safety of power grid operation.
  • Fire fighting equipment
    In firefighting equipment such as fire extinguishers, Nitinol gaskets can improve the reliability and durability of the equipment.
  • Aerospace
    Nitinol gaskets are used to manufacture lightweight and highly efficient structural components capable of maintaining stable performance in extreme environments.
  • Medical Devices
    Nitinol gaskets are also commonly used to manufacture medical devices such as surgical instruments and implants.
