Description

Medical-Grade Nitinol Tube for High-Precision Endoscopic Instruments

Medical-grade nitinol tube is engineered to deliver outstanding precision, flexibility, and durability for modern minimally invasive medical devices. Designed specifically for endoscopic instruments, our tubing offers superior superelastic performance, excellent dimensional control, and long-term reliability, ensuring optimal functionality in complex clinical environments.

Premium Materials & Strict Standards

Our medical-grade nitinol tube is produced using high-purity nickel-titanium alloy that meets stringent chemical composition and medical industry requirements. Manufacturing complies with ASTM F2063, Q/XB1516.1, and Q/XB1516.2, ensuring exceptional consistency, safety, and traceability across every production batch.

We provide multiple alloy grades to suit diverse clinical needs. Fully annealed grades feature Af ranges from 20°C to 40°C, while NiTi-SS superelastic grades deliver rapid elastic recovery with Af ranges from -5°C to 5°C. For body-temperature applications, our optimized NiTi-SS alloy with Af 33°C ±3°C offers highly predictable transformation behavior. Specialized low-temperature and wide-hysteresis alloys are also available to support complex medical designs.

High-Performance Features

Our medical-grade nitinol tube provides excellent superelasticity, allowing large reversible deformation without permanent damage. This ensures smooth navigation through tortuous anatomy and outstanding kink resistance, preventing lumen collapse during procedures.

Precision manufacturing delivers tight tolerances for outer diameter, inner diameter, and wall thickness, enabling seamless integration into advanced medical assemblies. In addition, the tubing exhibits superior corrosion resistance, long-term durability, and excellent biocompatibility, making it suitable for both implantable and disposable medical devices.

Endoscopic Applications

Medical nitinol tube is widely used in:

• Endoscopic guidewires and cannulas

• Flexible sheaths and delivery systems

• Stone retrieval baskets and biopsy tools

• Endoscopic stents and imaging components

Its non-magnetic nature ensures compatibility with MRI environments, while its superelastic response improves device control and procedural safety.
