Description
Nitinol Wire – Advanced Shapes – Memory Alloy for Precision Engineering
We specialize in manufacturing Nitinol products, a high-performance shape-memory alloy engineered to deliver unmatched flexibility and durability across precision applications. Ideal for medical, industrial, and consumer technologies, our NiTi wire combines superelasticity with precision engineering, offering tailored solutions from ultra-fine diameters (as thin as 0.025 mm) to fully customizable transformation temperatures (Af).
Why Ni Ti Wire Excels in Critical Applications
As a superelastic wire alloy, Ni Ti wire functions optimally between 0°C and 40°C, recovering from up to 8% strain without permanent deformation. This unique property, combined with a naturally formed low-friction oxide layer, makes it indispensable in a variety of use cases:
-
High-cycle components: Springs, actuators, shock absorbers
-
Attrition-sensitive systems: fishing tools, minimally invasive surgical equipment
-
Dynamic environments: Antennas and drive mechanisms exposed to repetitive motion
Medical-Grade vs. Industrial-Grade Nitinol Wire Solutions
We offer two specialized Ni Ti categories tailored to distinct application environments:
Medical-Grade Nitinol Wire
-
ASTM F2063 compliant (54.5–57 wt% Nickel)
-
Biocompatible for implants, stents, and surgical tools
-
Used in precision devices such as orthodontic archwires
Industrial-Grade Nitinol Alloys
-
Customizable NiTi formulations
-
Tunable Af temperatures from -10°C to 110°C
-
Engineered for thermal and mechanical cycling resistance
💡 Note: Ultra-thin profiles (≤0.1 mm) may offer narrower Af temperature windows due to production constraints.
