Nitinol Bar Stock

 

 

Product Introduction: Nitinol Bar Stock

Nitinol Bar Stock, a high-performance alloy composed of approximately 55 percent nickel and 45 percent titanium, is a unique material known for its shape memory effect and superelasticity. At Shaanxi CXMET Technology Co., Ltd., we supply premium-grade Nitinol Bar Stock for both medical and industrial applications worldwide. Our Nitinol bars are manufactured using vacuum induction melting followed by precision forging and rolling processes to ensure consistent composition, excellent mechanical performance, and superior surface finish.

As a trusted manufacturer of non-ferrous and refractory metals with more than 20 years of experience, we understand the critical requirements of global buyers in aerospace, medical device production, robotics, consumer electronics, and other high-tech sectors. With advanced processing equipment and a team of over 80 technical experts, Shaanxi CXMET delivers high-quality Nitinol materials that meet demanding international standards.

Features of Nitinol Bar Stock

• Shape Memory Effect that returns to its original form when heated

• Superelasticity allowing large recoverable strains without permanent deformation

• High corrosion resistance especially in body fluids and marine environments

• Biocompatibility for safe use in implantable medical devices

• High fatigue resistance under cyclic loading

• Excellent mechanical strength with flexible modulus

• Machinability under strict process controls for intricate parts

• Customizable transformation temperatures for precise engineering needs

Specifications of Nitinol Bar Stock

We also offer superelastic and cold-worked variants tailored to performance needs.

Applications of Nitinol Bar Stock

Nitinol Bar Stock is widely used in critical applications across multiple industries due to its unique thermomechanical behavior and material properties. Common uses include

• Medical Devices stents, guidewires, orthodontic archwires, bone anchors, implants

• Aerospace Engineering actuators, damping elements, adaptive wings

• Robotics and Automation sensor connectors, motion control elements

• Consumer Electronics eyeglass frames, flexible antenna components

• Oil and Gas Industry downhole tools, temperature-sensitive actuators

• Automotive Sector temperature-regulated valves, safety devices

Operating Environment

Nitinol Bar Stock performs well in a wide range of environmental conditions due to its corrosion resistance and phase transformation capabilities. It is suitable for

• Body-fluid contact and implantable environments

• Saline, acidic, or oxidative media

• Elevated mechanical stress and dynamic load conditions

• Cryogenic to high-temperature service, depending on alloy tuning

With proper heat treatment, the transformation temperature (Af) can be engineered to match operational demands in extreme or reactive environments.

Customization Available

We offer fully customizable Nitinol Bar Stock solutions to match your engineering requirements. Options include

• Tailored diameters and lengths

• Superelastic or shape-memory behavior optimization

• Specific phase transformation temperatures

• Nickel titanium composition adjustments

• Precision tolerances and surface finishing

• Small batch or bulk volume supply

All custom orders are supported with technical consultation and detailed quality documentation.

Key Advantages of Nitinol Bar Stock

• Unique combination of superelasticity and shape memory

• Longer fatigue life than stainless steel in cyclic applications

• Enhanced corrosion resistance in aggressive environments

• Lightweight with high strength-to-weight ratio

• Eliminates the need for complex actuation systems

• Supports miniaturization in medical and electronic devices

• Reduces overall component count and increases device reliability

Nitinol offers an unmatched solution where performance, adaptability, and durability are critical.
