Nitinol Wire & Rod Description
Nitinol Wire & Nitinol Rod are the fabricating products of nickel-titanium alloy. Nitinol is well known for its thermo-mechanical properties of superelasticity and shape memory effect. Shape memory refers to the ability of Nitinol to undergo deformation at one temperature and then recover its original, under-formed shape upon heating above its transformation temperature.
Super elasticity occurs at a narrow temperature range just above its transformation temperature; in this case, no heating is necessary to cause the under-formed shape to recover, and the material exhibits enormous elasticity, some 10-30 times that of ordinary metal.
Nitinol Wire & Nitinol Rod Features:
- Values listed are for full martensite to austenite transition.
- Hysteresis can be significantly reduced by partial transformation or ternary alloys.
- Similar to 300 series stainless steel or titanium
- Highly nonlinear with temperature
All incoming Nitinol raw materials are ensured that they meet proprietary internal specifications for chemistry, ingot transformation temperature, material homogeneity, and microstructure. Optimized to promote an exceptionally smooth and uniform surface finish quality, all wire products utilize a proprietary single and multi-crystalline diamond drawing die technology. Medical grade Nitinol Wire may be purchased in the cold worked (CW) or the super-elastic condition (SE) and after the correct superelastic heat treatment will accommodate strain up to 8% without permanent deformation at body temperature.
