FOTMA Premium Nickel Alloy Wires: Where Precision Meets Durability

FOTMA nickel alloy wires stand out as critical materials for high-temperature, corrosive, and high-stress environments, thanks to their exceptional performance and precision engineering. Designed for advanced industries such as electronics, medical devices, and aerospace, our wires combine superior conductivity, fatigue resistance, and stability in extreme conditions, making them the ideal choice for delicate component manufacturing.

Product Features:

1. Ultra-Fine Diameter & High Surface Precision
   • Diameter range: 0.01 mm – 5.0 mm (custom ultra-fine sizes available).
   • Surface roughness: Ra ≤ 0.2 µm (mirror polishing optional), meeting requirements for high-sensitivity components like micro-sensors and precision coils.
2. Elastic-Plastic Dual Advantage
   • High elastic modulus (≥190 GPa) paired with ductility (20%-40% elongation), ideal for springs, connectors, and applications requiring repeated deformation.
3. Stable Conductivity & Low Resistivity
   • Resistivity as low as 0.096 µΩ·m (e.g., Nickel 200), enabling efficient energy transfer for battery tabs, electrical contacts, and more.
4. Hydrogen Embrittlement & Radiation Resistance
   • Special alloy formulations (e.g., Inconel® 600) resist hydrogen penetration and radiation damage, suitable for nuclear and hydrogen energy systems.
5. Biocompatibility & Sterile Surfaces
   • Medical-grade Ni-Ti alloy wires (e.g., Nitinol) comply with ISO 13485, used for cardiovascular stents, orthopedic guide wires, and implants.
