Product Overview
This Puratronic™ nickel wire delivers 99.994% ultra-high purity with a precise 0.25mm (0.01in) diameter, engineered for applications demanding superior conductivity, thermal stability, and corrosion resistance. The wire’s uniform composition ensures consistent performance in environments where trace impurities could compromise results. Its fine gauge allows for intricate configurations while maintaining structural integrity under thermal cycling or mechanical stress. The Puratronic™ grade guarantees minimal metallic and non-metallic contaminants, making it ideal for sensitive analytical, electronic, or high-temperature applications. The wire’s smooth surface finish reduces oxidation risks and enhances solderability, while its ductility enables easy shaping without compromising electrical properties. Available in 50m, 10m, and 2m lengths to accommodate both large-scale and precision requirements, this nickel wire is packaged to prevent contamination during storage and handling. The material’s low thermal expansion coefficient and high melting point (1455°C) ensure dimensional stability across temperature extremes, while its ferromagnetic properties at room temperature make it suitable for specialized electromagnetic applications. Each batch undergoes rigorous spectroscopic analysis to verify purity, with certification provided for traceability in quality-critical workflows.
FAQs
1. What is the maximum operating temperature for this Puratronic™ nickel wire?
This 99.994% nickel wire maintains structural integrity up to 1200°C in inert atmospheres, though prolonged exposure above 600°C may accelerate oxidation in air. For high-temperature applications, consider using argon or vacuum environments to preserve surface purity.
2. Can this wire be used for resistance heating applications?
Yes, the wire’s consistent resistivity (6.99 μΩ·cm at 20°C) and high melting point make it suitable for resistance heating elements, though its relatively low resistivity compared to nichrome may require longer lengths for equivalent heat output.
3. How does the Puratronic™ grade differ from standard nickel wire?
Puratronic™ grade ensures 99.994% minimum purity with tightly controlled trace element limits (e.g., <10 ppm Fe, <5 ppm Cu), whereas standard grades typically range from 99.0-99.6% purity and may contain higher levels of impurities that affect performance in sensitive applications.
4. What is the recommended storage method to prevent oxidation?
Store the wire in its original sealed packaging with desiccant at room temperature (15-30°C) and <50% humidity. For long-term storage, vacuum-seal with oxygen absorbers or use argon-purged containers to minimize surface oxidation.
5. Is this wire compatible with glass-to-metal sealing applications?
Yes, the wire’s thermal expansion coefficient (13.3 µm/m·K) closely matches borosilicate glass, making it suitable for hermetic seals when using compatible glass compositions and proper sealing techniques.
