High-Purity Nitinol Wire for Medical Devices ASTM F2063

High-purity Nitinol wire is a premium alloy revolutionizing medical devices with its exceptional shape memory and superelastic properties. Composed of an ultra-clean nickel-titanium blend with over 99.9% purity, this wire delivers superior performance with minimal impurities that could compromise functionality. Its lightweight, corrosion-resistant, and biocompatible characteristics make it ideal for implants and tools requiring flexibility and durability within the human body.

Our high-purity Nitinol wire begins with approximately 50% nickel and 50% titanium, sourced from premium suppliers to maintain carbon levels below 0.02% and ultra-low oxygen content. This exceptional purity enhances biocompatibility and reduces fatigue, enabling the wire to endure millions of cycles without failure. Rigorous testing, including spectrometry, ensures each batch meets the stringent 99.9% purity standard.

• Superior shape memory and superelastic properties
• Exceptional corrosion resistance with minimal pitting
• Reduced nickel leaching for safer long-term implants
• Customizable transition temperatures (-20°C to 100°C)
• Available in diameters from 0.05mm to 3mm
• FDA-compliant for medical applications

High-purity Nitinol wire excels in medical device applications including vascular stents that expand precisely within arteries, flexible guidewires for minimally invasive procedures, orthodontic wires for gentle tooth movement, and surgical clips requiring precision. Its biocompatibility and corrosion resistance make it particularly valuable for implants like heart valves and blood clot filters.

The Nitinol medical device market reached approximately $4.1 billion in 2024, with high-purity wire specifically projected to grow from $600 million in 2025 to $1.5 billion by 2033 at a 9% CAGR. This growth is driven by increasing demand for minimally invasive surgical procedures, advancements in medical robotics, and expanding applications in electric vehicle thermal management systems.
