Product Overview
This Puratronic™-grade nickel wire delivers unmatched purity at 99.995% (metals basis), ensuring minimal impurities for sensitive laboratory applications. The 0.5mm (0.02in) diameter provides optimal balance between flexibility and structural integrity, making it ideal for intricate electrical connections, thermal conductivity tests, or as a corrosion-resistant component in experimental setups. Engineered with a smooth, uniform surface finish, this wire minimizes oxidation risks while maintaining consistent performance across high-temperature environments. Its high ductility allows for precise shaping without compromising mechanical strength, while the Puratronic™ certification guarantees traceability and batch-to-batch consistency. The wire’s low thermal expansion coefficient ensures dimensional stability during thermal cycling, a critical factor in calibration and measurement applications. Available in 1m and 5m lengths, this nickel wire is packaged to prevent contamination, preserving its ultra-high purity until use. The material’s inherent magnetic properties further extend its utility in specialized electromagnetic experiments, while its biocompatibility makes it suitable for certain medical research applications where metal purity is paramount.
FAQs
1. What is the maximum operating temperature for this nickel wire?
This Puratronic™ nickel wire maintains structural integrity up to 1,400°C in inert atmospheres, though oxidative environments may reduce this threshold to approximately 600-800°C depending on exposure duration.
2. Can this wire be soldered or welded to other metals?
Yes, but it requires nickel-compatible fluxes and high-temperature soldering techniques due to its high melting point (1,455°C). For welding, TIG or laser methods are recommended with appropriate filler materials.
3. How does the Puratronic™ grade differ from standard nickel wire?
The Puratronic™ designation indicates a minimum 99.995% purity with strictly controlled trace element limits (typically <10ppm total metallic impurities), whereas standard grades may contain 99.5-99.9% nickel with higher impurity levels.
4. What precautions should be taken during storage to maintain purity?
Store in the original sealed packaging with desiccant packs at room temperature, away from acidic vapors or oxidizing agents. Avoid physical contact with bare hands—use gloves to prevent oil contamination.
5. Is this wire suitable for vacuum chamber applications?
Yes, its low outgassing properties make it appropriate for high-vacuum environments, though pre-cleaning with acetone or isopropyl alcohol is recommended to remove surface contaminants before installation.
