Active Austenite Finish Temperature of Nitinol Tube
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 of Nitinol Tube
|Upper Plateau Stressσload MPa||Active Af ℃|
* Superelastic properties are measured per Test Method F 2516 at room temperature （22+/-2℃）
* Applicable Standard: ASTM F2633
Surface Finish of Nitinol Tube
-Outer surface: Black oxide or Center-less Ground.
-Inner surface: Etched or oxide.
Other finishes can be discussed with EdgeTech Industries.
Nominal Dimensions and Tolerances of Nitinol Tube
|Nominal OD/ID mm (in)||Diameter tolerance mm (in)|
|≤1.5 (0.059)||+/-0.025 (+/-0.001)|
|1.5<OD≤6.5 (0.059~0.256)||+/-0.050 (+/-0.002)|
|6.5<OD≤10 (0.256~1.2)||+/-0.075 (+/-0.003)|
* Other variation in OD and ID can be discussed with Oasis Materials.
Length of Nitinol Tube
Nitinol tube can be delivered in either exact length or random length. For random length orders, a maximum and minimum length shall be discussed with us.
Requirements on Straightness, Permissible Outer and Inner Surface Imperfections of Nitinol Tube hall be discussed with OMT. Please send us your request to email@example.com for any needs on nitinol tubes.
