Nitinol Hypotube 0.3×0.2mm | Superelastic Precision Tube

Description

Nitinol Hypotube 0.3×0.2mm: Precision Superelastic Power

Introducing our top-performing Nitinol Hypotube: 0.3mm outer diameter, 0.2mm inner diameter. This tiny tube delivers giant performance. It uses medical-grade Superelastic Nitinol. This material offers unique abilities essential for advanced medical devices and demanding micro-engineering.

High-Quality Superelastic Nitinol Alloys

We manufacture this tube from the highest-quality Nitinol alloys, including common medical grades like ASTM F2063. These alloys guarantee superelasticity, biocompatibility, and precision performance. Strict melting, drawing, and annealing controls ensure that every batch delivers consistent results. At body temperature, this tube maintains its superelastic behavior reliably, making it ideal for implants, guidewires, and surgical tools.

Precision Dimensions for Micro-Applications

With its 0.3mm outer diameter and 0.2mm inner diameter, this Nitinol Hypotube is ideal for minimally invasive medical applications. Precision drawing and finishing create smooth inner and outer surfaces, reducing friction for seamless device operation. We offer custom lengths, making it the perfect choice for highly specific medical and micro-device manufacturing.

Unmatched Superelasticity and Shape Memory

This Nitinol Hypotube withstands significant bending and deformation, returning reliably to its original shape every time. Its superelastic behavior eliminates the risk of plastic deformation common with stainless steel, providing kink resistance and precise torque and pushability for guidewires and catheters. In addition, it offers shape memory properties. When cooled, the tube becomes highly flexible for reshaping, and upon heating, it returns to its original form — ideal for next-generation medical device deployment.

Applications for the Nitinol Hypotube

• Guidewires & Catheters: Enables precise navigation in neurovascular, cardiovascular, and peripheral interventions.

• Micro-Delivery Systems: Transports drugs, fluids, or micro-tools through narrow body channels.

• Endoscopic Instruments: Enables steerable elements for precision procedures like ERCP or NOTES.

• Stent Delivery Systems: Supports accurate positioning and deployment of vascular stents.

• Orthodontic Archwires: Provides gentle and continuous tooth-moving forces (micro-tubes for specialized uses).

• Microfluidics & Sensors: Acts as a conduit for fluids or a sensor element in lab-on-a-chip devices.

• Robotics & Actuation: Enables compact, reliable actuators for micro-robotics and aerospace applications.

Understanding Nitinol and Heat Treatment

While many metals harden when heated, Nitinol behaves differently. The drawing and cold working process significantly strengthens the tube and defines its superelastic properties. Precise aging treatments fine-tune its characteristics, making it ideal for medical applications. Excessive heating can reduce its superelastic performance, making precision processing essential.

Quality You Can Trust

Manufactured under an ISO 13485 medical device quality system, every Nitinol Hypotube undergoes stringent quality controls. We test critical dimensions, mechanical properties, tensile strength, elongation, and surface finish. Material composition is verified to meet ASTM F2063 specifications. This guarantees a reliable, precision-engineered component for your medical or micro-mechanical designs.
