Seamless nickel titanium alloy tube

Requirements for medical thin-walled nickel titanium tubes (hypotubes): ultra-high dimensional accuracy, smooth inner wall, electrolytic polishing, low nickel precipitation, in accordance with ASTM F2063 standard;

Industrial grade thin-walled nickel titanium pipes focus on mechanical properties and corrosion resistance, with no mandatory requirements for biocompatibility.

Pengchengrui Technology in Huizhou City specializes in supplying high-precision thin-walled nickel titanium pipes. The pipe material has excellent superelasticity and shape memory properties, outstanding corrosion resistance, and good biocompatibility. It can achieve extremely small wall thickness and controllable dimensional tolerances through precision machining, and supports electrolytic polishing treatment. The product is compatible with interventional catheters, stent substrates, minimally invasive surgical instruments, industrial sensing and precision automation equipment. From raw material control to one-stop delivery of finished product processing, customized outer diameter, wall thickness, phase change temperature, and surface technology can be provided as needed, ensuring stable supply of medical grade and industrial grade thin-walled nickel titanium pipes. Medical device manufacturers and research institutions are welcome to discuss cooperation.
