High-Purity Nitinol Wire (ASTM F2063) for Medical Devices

Description

High-Purity Nitinol Wire (ASTM F2063)

Ultra-Clean Materials for Medical Reliability

Our High-Purity Nitinol Wire is engineered with an approximately 50% nickel and 50% titanium composition, delivering exceptional consistency and performance for medical-grade applications. Thanks to advanced purification control, impurity levels remain extremely low, with carbon content below 0.02%, alongside tightly controlled oxygen and trace elements.

This ultra-clean chemistry results in a highly stable nickel-titanium alloy that meets the strict safety, performance, and biocompatibility requirements demanded by modern medical devices.

ASTM F2063 Certified Performance

Manufactured in full compliance with ASTM F2063, this High-Purity Nitinol Wire is designed for wrought nickel-titanium shape memory alloys used in medical applications. Two primary functional grades are available:

• Superelastic Nitinol Wire
  Offers exceptional elasticity and fatigue resistance. It withstands large deformations while fully recovering its original shape. Tensile strength typically ranges from 900 MPa to 1600 MPa, ensuring both flexibility and mechanical reliability.

• Shape Memory Nitinol Wire
  Activates when exposed to heat, returning to a preset shape at a defined transformation temperature.

  • Superelastic grades: –20°C to 40°C

  • Shape memory grades: 0°C to 100°C
    These temperatures can be precisely customized, including optimization for human body temperature, making the wire ideal for implantable medical devices.

Exceptional Corrosion Resistance & Biocompatibility

A naturally formed titanium-rich oxide surface layer provides outstanding resistance to corrosion. The wire performs reliably in bodily fluids, saline environments, and mildly acidic conditions. This surface chemistry ensures long-term stability, reduced ion release, and excellent biocompatibility, critical for implantable and long-term-use medical products.

Product Advantages of High-Purity Nitinol Wire

With a purity level exceeding 99.9%, this High-Purity Nitinol Wire excels in three core performance areas:

• Shape Memory Effect – Recovers its original form when heated after deformation

• Superelasticity – Allows extreme flexibility without permanent deformation

• Biocompatibility – Well tolerated by the human body, minimizing adverse reactions

These properties enable the development of minimally invasive, durable, and highly reliable medical devices, addressing complex clinical design challenges.
