Description of Nickel Titanium Niti Wire, Nitinol wire
Nitinol wire, a Nickel-Titanium (NiTi) alloy, is renowned for its superelasticity and shape memory effect. This advanced material has revolutionized multiple industries, particularly medical, aerospace, and robotics, due to its unique ability to return to a predetermined shape after deformation. With its exceptional properties, Nitinol wire is a vital component in numerous high-performance applications.
Characteristics of Nitinol wire, rod, and bar
Superelasticity – Allows it to undergo significant deformation and instantly return to its original shape.
Shape Memory Effect (SME) – Enables it to revert to a pre-defined shape upon heating.
Corrosion Resistance – Highly resistant to oxidation and biological environments.
High Fatigue Strength – Maintains performance even under repeated stress cycles.
Biocompatibility – Safe for medical implants and biomedical applications.
SE Nitinol NiTi alloy Wire, rod, and bar composition
Nitinol wire is typically made of 55–56% nickel (Ni) and 44–45% titanium (Ti). The exact composition depends on the desired properties of the material.
