Premium SMA Wire Materials

• Core Composition: Crafted from high-purity Nickel Titanium alloy (Nitinol), this Shape Memory Alloy (SMA) ensures superior elasticity and shape memory functionality.

• Precision Alloying: Our proprietary composition guarantees dependable superelasticity and thermal responsiveness for consistent wire behavior.

• Medical-Grade Sourcing: Materials meet strict biocompatibility and traceability standards, essential for critical healthcare devices.

---

Advanced Black Oxide Surface Technology

• Controlled Oxidation: The black oxide layer is formed through a proprietary thermal process, creating a uniform, matte black surface.

• Low Friction: This finish dramatically reduces drag within catheters and delivery systems, improving maneuverability and tactile feedback.

• Corrosion & Glare Resistance: Designed to resist bodily fluids and sterilization cycles, while minimizing visual interference during procedures.

• Strong Bonding: The oxide layer adheres seamlessly to the Nitinol base, preventing flaking during aggressive use or flexing.
