Let’s get into it…

What is Ni200 Wire?

Nickel 200 wire, or Ni200, is a commercially pure nickel wire that contains at least 99.6% nickel.The high-purity wire is known for its excellent mechanical properties and resistance to corrosion.

In addition to nickel, it contains trace amounts of other elements that enhance its strength and durability without compromising its conductivity.

The properties that make 99.6% nickel content so desirable include:

  • Exceptional Thermal Conductivity: Heat is efficiently transferred by Ni200 wire, which is crucial for applications requiring rapid thermal dissipation.
  • Electrical Conductivity: In electronic applications where superior and consistent electrical performance is required, nickel provides excellent electrical conductivity.
  • Corrosion Resistance: Wire made of Ni200 is highly corrosion-resistant, especially in alkaline environments, making it suitable for handling and processing caustic solutions.
  • Magnetic Properties: Nickel 200 exhibits magnetic properties at room temperature, allowing it to be used in electromagnetic devices.


These characteristics make Ni200 wire a preferred choice in settings where material purity is paramount for the application’s success.

Ni200 Wire in Industry Applications

Ni200 wire’s versatility is showcased across various industries, each capitalizing on its specific properties for diverse applications:

  • Electronics: Due to its excellent conductivity and stability, Ni200 wire is widely used in this sector for battery connections, lead wires, and in devices that require precise thermal management.

  • Aerospace: In the aerospace industry, Ni200 wire is valued for its ability to perform under extreme conditions. Engine sensors and electrical systems use it to withstand high temperatures and corrosive environments.

  • Manufacturing: Due to its resistance to caustic environments, Nickel 200 is an ideal material for chemical handling equipment, processing vessels, and valves.

  • Food Processing: Due to its non-reactive nature, it can be used in food processing equipment without imparting any taste or contaminants.

As a staple in scenarios demanding the highest quality, Ni200 wire offers distinct advantages such as longevity, reliability, and purity.

Soft vs. Hard Ni200 Wires

It is important to distinguish between soft and hard tempers when it comes to Ni200 wires. Soft Ni200 wire, also known as annealed wire, is characterized by its ductility and ease of use. A process of heating and cooling realigns the wire’s internal structure to make it more malleable. Due to its flexibility, it is ideal for applications requiring intricate shaping and bending, such as electronic assemblies and custom battery connections that must be handled without breaking.

Hard or unannealed Ni200 wire, however, has not undergone this softening process, so it is stiffer and more rigid. Cold-worked Ni200 wire retains much of its strength, making it suitable for applications requiring structural integrity and minimal elongation. In high-temperature furnaces or harsh environments, it’s often used for structural components that must maintain their shape under mechanical load or thermal expansion.

Ultimately, the choice between soft and hard Ni200 wires depends on the application. Ni200 wire is ideal for projects that require a high degree of formability, while hard Ni200 wire is better for applications that require strength and shape retention.

Gauges of Ni200 Wire and Their Uses

The gauge of Ni200 wire, which measures its diameter, plays a pivotal role in determining its use. The Crazy Wire Company provides a broad spectrum of gauges to accommodate various industrial needs.

  • Fine Gauges (0.08mm to 0.3mm): Ni200 wires of this gauge are typically used in precision electronics where high-quality connections and detailed work are needed. When the wire must respond quickly to thermal changes without adding significant bulk, the thinner wire is perfect for vaping devices or sensitive temperature probes.

  • Medium Gauges (0.35mm to 0.5mm): The wires in this range strike a balance between flexibility and durability. A moderate level of resistance is required for heating elements, battery terminals, and internal connections within power storage devices.

  • Thick Gauges (0.64mm to 0.7mm): The thickest gauges of Ni200 wire are often used in applications where mechanical properties are equally important as electrical properties. Structural components in aerospace engineering, robust electrical heating elements, and electromagnets with high strength are examples.

Working with Ni200 Wire: Tips and Techniques

Working with Ni200 wire requires careful handling to maintain its integrity and performance:

  • Annealing: You can anneal hard Ni200 wire to soften it for shaping by carefully heating it with a torch and allowing it to cool.
  • Cutting: Use sharp, precise wire cutters for clean cuts to prevent wire fraying, especially in fine gauges.
  • Shaping: When bending or shaping Ni200 wire, use appropriate tools such as pliers and wire jigs to avoid kinks and maintain uniformity.


By understanding the nuances of different gauges and tempers, users can select and work with Ni200 wire more effectively, leading to better performance and longevity in their specific applications.

Expert Tips for Handling and Working with Ni200 Wire

Working with Ni200 wire requires a keen understanding of its properties to maintain its quality and integrity. Here are some expert tips:

  1. Proper Storage: In order to prevent any form of corrosion or degradation, Ni200 wire should be stored in a clean, dry environment.
  2. Handling with Care: In order to avoid transferring oils or contaminants onto the wire, it is always recommended to handle the wire with clean hands or gloves.
  3. Straightening: If you want to straighten Ni200 wire, you should use either a draw plate or nylon-jawed pliers to gently pull the wire through, realigning it without causing stress fractures in the wire.
  4. Soldering: You should use a nickel-specific flux when soldering Ni200, and you should also be aware of the temperature as excessive heat can cause the wire to become brittle.

How Ni200 Differs from NiFe and Ni

Ni200, NiFe, and pure nickel (Ni) serve distinct purposes in various applications. With at least 99.6% nickel content, Ni200 offers exceptional electrical and thermal conductivity, making it ideal for applications such as battery components and electrical connectors.

In contrast, NiFe alloys have unique magnetic properties due to their combination of nickel and iron. The controlled magnetic permeability of NiFe alloys makes them suitable for electromagnetic applications, such as inductors and transformers.

While pure nickel is similar to Ni200 in purity, it usually refers to a non-specific alloy and has a broader range of applications due to its corrosion resistance and ductility. The material is used for a variety of purposes, from plating and coatings to complete structural components.

Selecting the right material for your needs requires an understanding of these differences. While NiFe’s magnetic properties are unmatched for electromagnetic applications, Ni200’s high purity level offers advantages in applications requiring corrosion resistance and thermal properties.

For any project that requires high-purity nickel, selecting the right Ni200 wire is crucial. Especially where electrical and thermal performance are critical, Ni200 stands out because of its exceptional properties.
