The magic of our cobalt-doped Nitinol wire lies in its carefully crafted composition. The base alloy combines nickel (54.5-57.0%) and titanium, delivering the superelasticity and shape memory that Nitinol is known for. Adding 0.1-0.5% cobalt ramps up the stiffness and tensile strength, making it ideal for applications where standard Nitinol might not be rigid enough. The transformation temperature range (-20°C to 40°C) is optimized for superelasticity or shape memory in demanding settings, from surgical implants to industrial components.

Compared to materials like stainless steel or pure titanium, our cobalt-doped Nitinol wire is in a league of its own. Stainless steel is strong but lacks shape memory and can be too rigid for dynamic applications. Pure titanium is biocompatible but doesn’t offer the stiffness or fatigue resistance of our Nitinol. Our wire’s corrosion resistance is outstanding, standing up to bodily fluids or harsh industrial environments. With an elongation range of 8-12%, it balances rigidity and flexibility, making it perfect for high-stress uses like bone fixation devices or aerospace actuators.
