nitinol tube od 0.7mm

Nickel titanium tubing is like a 'memory rich, ultra durable metal hose' - it can restore its preset shape at specific temperatures (such as automatically opening a medical stent after implantation), and withstand 8% -10% of large deformations (20 times that of ordinary stainless steel). It can be bent, stretched, and immediately restored upon release. It is also non-toxic, corrosion-resistant, and has high strength, making it particularly suitable for scenarios that require 'repeated deformation without failure' or 'precise shape control'.

nitinol tube od 0.7mm Material : Nickel titanium binary alloy, the composition ratio determines the core properties (such as phase transition temperature, elasticity), and can be customized according to needs;
Two main characteristics of niti tubes:
1. Shape memory: deform at low temperatures and automatically restore its original shape when heated to the "phase transition temperature" (customizable -20 ℃~100 ℃);
2. Super elasticity: When above the phase transition temperature, it can withstand extremely large strains (8% -10%), recover 100% after unloading, and have no permanent deformation;
Additional advantages: biocompatibility (non-toxic and non discriminatory, suitable for in vivo implantation), corrosion resistance (superior to stainless steel), fatigue resistance (with a lifespan of up to 10 million cycles), high strength (tensile strength ≥ 1000MPa);
Core application scenarios: medical (stents, orthodontic archwires), industrial (flexible fixtures, aviation components), consumer electronics (folding screen hinges, wearable devices) - as long as customers have the needs of "recovering after deformation", "not damaged by repeated force", and "requiring biological safety/corrosion resistance", this is the target scenario for nickel titanium tubes.

Compared with ordinary stainless steel pipes, nickel titanium pipes are not 'hard to withstand pressure', but 'elastic to adapt' - stainless steel can be bent once and become useless, while nickel titanium pipes can be bent to 1.1 times their own length and then bounce back; Compared with rubber pipes, nickel titanium pipes have higher strength, high temperature resistance, and can be used for a long time in high-pressure and corrosive environments, which is also the core reason why they can replace traditional materials.

FAQs about Purchasing Nickel Titanium Tubes

Q1: How much is the price higher than ordinary stainless steel?

A: The unit price is about 5-10 times that of stainless steel, but the comprehensive life cost is only one-third. For example, industrial fixtures are replaced 5 times a month; Nickel titanium fixtures can be used for 5 years,  saving over 90% of maintenance costs.

Q2: Will superelasticity decay with the number of uses?

A: Our product has undergone special heat treatment and has been tested 1 million times under 8% strain, with a recovery rate of over 99.5%, far exceeding industry standards.

Q3: How to ensure product quality?

A: The product complies with GB/T 24627-2023 (Chinese standard) and ASTM F2063 (international standard), and provides material analysis reports and performance test data for each batch.
