Specification: OD(0.5-5)mm*WT(0.05-0.3)mm*L
Application:mainly in medical device industry
Nitinol capillary tube used in implantable medical devices including Heart valves, peripheral vascular stents, cardio stents, neurovascular stents etc.
Medical devices use requires high quality surface on Nitinol tubing. The technology and tube making processes developed by Vascotube have been perfected over many years of practice. Using our experience, combined with new technologies and custom made machinery, we have been able to develop a drawing process that avoids the need for slurry cleaning, chemical cleaning or mechanical removal operations on the inner surface of the drawn tube. Our process allows us to attain a roughness value of Ra 0,1 µm.
Active Austenite Finish Temperature
The austenite finish temperature of the finished tube (Active Af) with outer diameter in the range of 0.3 to 3.0 mm (0.012 to 0.12 in.) shall be measured on representative full round tube sample(s) using the bend and free recovery method described in Test Method ASTM F 2082-15.
Mechanical Properties
