FAQs About This Wire

Can Nickel 200 Wire Be Used In Jewelry Making?

It is possible to use Nickel 200 wire in jewelry making due to a few intrinsic properties that make it a viable option. As a result of its 99.6% nickel purity, this wire is highly appreciated for its hypoallergenic properties. This minimises allergic reactions in wearers when making earrings, necklaces, bracelets, and other items that have direct skin contact. In addition, Nickel 200’s commendable corrosion resistance ensures that jewelry made from it will remain attractive and tarnishing-free for many years to come.

The malleability and ductility of this material make it an excellent choice for artisans who wish to create intricate designs without compromising structural integrity. Nickel 200 wire has a high melting point and is stable under various conditions. This makes it ideal for jewelry items exposed to different elements and conditions. The wire can therefore be effectively used to create pieces that are both visually appealing and safe for those with sensitive skin. This product conforms with the meticulous requirements of jewelers, while ensuring wearers’ longevity and reduced allergy risk.

Are There Any Limitations To Using Nickel 200 Wire?

  • Low Strength at High Temperatures: Nickel 200 wire may lose some mechanical strength when used at elevated temperatures.
  • Hardening Limitations: Unlike some alloys, Nickel 200 wire does not harden by heat-treating and can only be strengthened by cold working, which may limit its use in applications requiring higher strength.
  • Corrosion in Reducing Environments: While it’s corrosion-resistant in various settings, it might corrode in reducing, sulfur-containing environments.
  • Limitations in High-Temperature Applications: Nickel 200 wire has a limitation in high-temperature applications (above approximately 315°C or 600°F) due to the potential for the graphite to form, which might be detrimental in some uses.
  • Stress-Corrosion Cracking: It might be susceptible to stress-corrosion cracking in certain environments, particularly in the presence of chlorides and other halides.
  • Magnetic Permeability: Under certain conditions, the magnetic permeability of Nickel 200 wire might be higher, which could be a limitation in applications that require non-magnetic materials.
  • Cost: Nickel 200 wire might be more expensive than other alternatives, which might impact budget-sensitive projects.
  • Welding Considerations: Although it’s weldable, careful attention is needed to avoid issues like hot cracking during welding operations.
  • Restricted in Acidic Environments: Although it resists neutral and alkaline corrosive environments, Nickel 200 wire may corrode in certain acidic or sulfurous atmospheres.

Is Nickel 200 Wire Magnetic?

Nickel 200 wire is characteristically considered non-magnetic due to its nominal magnetic permeability, especially at ambient temperatures. This low magnetic permeability makes it an advantageous material in various applications where magnetic interference needs to be minimised, such as in certain electronic devices, sensors, and some jewelry applications. However, it is vital to note that while it exhibits minimal magnetic properties at room temperature, the magnetic permeability of Nickel 200 wire can increase substantially as temperatures decrease towards cryogenic levels.

Moreover, under specific conditions or when subjected to particular treatments, such as cold working, the wire’s magnetic properties might be slightly enhanced. It’s pertinent to consider these properties in scenarios where absolute non-magnetic characteristics are crucial, ensuring the material’s minimal magnetic nature does not impair the function of the end product. The nuanced magnetic characteristics of Nickel 200 wire thereby require thoughtful consideration and understanding to effectively leverage its utility in various applications while mitigating potential magnetic interference.
