Product Overview
This high-purity 99.98% annealed nickel wire is engineered for precision and reliability in laboratory settings. With a 0.5mm diameter, it delivers consistent electrical conductivity while maintaining exceptional flexibility, making it ideal for intricate experimental setups. The annealing process enhances its ductility, reducing brittleness and ensuring ease of handling during delicate procedures. Its corrosion-resistant properties extend its lifespan, even in harsh chemical environments, while its high melting point (1455°C) allows for stable performance in elevated temperature applications. The wire’s uniform composition minimizes impurities, guaranteeing reproducible results in sensitive measurements. Whether used for electrode fabrication, resistance heating, or as a conductive component in custom apparatus, this nickel wire provides the durability and purity required for high-accuracy scientific work. The material’s low thermal expansion coefficient further ensures dimensional stability across temperature fluctuations, reducing experimental variables. Available in convenient lengths of 5m, 25m, and 100m to accommodate both small-scale testing and bulk requirements.
FAQs
1. What is the melting point of this nickel wire?
The melting point of this 99.98% pure nickel wire is approximately 1455°C, making it suitable for high-temperature applications without structural degradation.
2. Can this wire be used in acidic or alkaline environments?
Yes, the high-purity nickel composition offers excellent corrosion resistance in both acidic and alkaline conditions, though prolonged exposure to strong oxidizing agents may require additional protective measures.
3. Is this wire compatible with standard lab power supplies?
The wire’s low electrical resistivity (6.99 μΩ·cm at 20°C) ensures compatibility with most laboratory power supplies, but always verify current-carrying capacity based on your specific experimental setup.
4. How should this nickel wire be stored to prevent oxidation?
Store the wire in a dry, sealed container with desiccant packets to minimize exposure to moisture. For long-term storage, consider vacuum-sealing or using argon-filled packaging to prevent surface oxidation.
5. What alternatives exist if I need higher temperature resistance?
For applications requiring higher temperature resistance than nickel, consider tungsten wire (melting point 3422°C) or molybdenum wire (2623°C), though these alternatives may have different electrical and mechanical properties.
