NiFe52 Round Wire

The Crazy Wire Company are best know as suppliers of top quality NiFe52 round wire. We have enormous stock levels at all times, as we use this wire to weave our top quality woven mesh products. Our brilliant staff are experts in producing our spools of round wire on our 6 rapid action winding machines. All spools are produced to carry a little extra length to make up for any waste when handling the product.

NiFe52 round wire, measuring 0.3mm (29 AWG) in diameter, is a specialised type of nickel wire composed of approximately 52% nickel. Due to its unique combination of properties, this product is suitable for various applications in various industries. In environments where corrosive elements might be present, the NiFe52 round wire is an ideal choice because of its exceptional corrosion resistance. The chemical processing and marine industries particularly benefit from this characteristic.

Besides being highly thermally conductive, this wire also has a low resistance to oxidation. The result is that it is a highly effective heat dissipator, which makes it an excellent choice for electronic components and heat exchangers. NiFe52 round wire has excellent thermal properties, making it ideal for use in heating elements, where efficient and consistent heat transfer is required.

Specification of Wire:

  • Diameter – 0.3mm (300 Micron – 29AWG)
  • Ohms/m – 5.99

FAQs About This Wire

How Does NiFe52 Round Wire Perform In Cold Environments?

NiFe52 round wire performs exceptionally well in cold environments, maintaining its key properties under low temperatures. The high nickel content in this alloy contributes to its excellent low-temperature performance, ensuring that the wire remains ductile and does not become brittle when exposed to cold conditions. This is particularly important in applications where the material is subject to mechanical stress or needs to maintain its structural integrity in cold climates.

The electrical and magnetic properties of NiFe52 round wire are also largely unaffected by cold temperatures. This means that its electrical resistance remains stable, and its magnetic permeability does not significantly diminish, making it a reliable choice for electronic and magnetic applications in cold environments.

Additionally, the wire’s corrosion resistance is an advantage in cold, potentially moist conditions, where other materials might suffer from increased corrosion rates. This resistance ensures a longer lifespan and consistent performance, even in challenging environmental conditions.

Can NiFe52 Round Wire Be Soldered Or Welded Easily?

NiFe52 round wire can be soldered or welded, but its special composition requires specific welding techniques. With the right approach, welding and soldering NiFe52 wire can be successfully managed despite the high nickel content.

Soldering nickel alloys requires a flux that is compatible with those alloys. Depending on the wire’s thermal properties, the soldering temperature may need to be higher than standard soldering processes. To achieve a strong solder joint, it is also crucial that the wire is clean and free of oxides or contaminants.

It is important to choose welding parameters and techniques carefully when welding NiFe52 round wire. A tungsten inert gas (TIG) or metal inert gas (MIG) welding technique is often recommended. A nickel alloy-compatible filler material is crucial to preventing cracking during welding and ensuring a strong bond. It may also be beneficial to apply heat treatments before and after welding in order to reduce stresses and ensure the wire’s integrity.

NiFe52 round wire should ideally be soldered and welded by experienced technicians who understand nickel alloy properties. In order to achieve reliable and high-quality joints, it is essential to have the right equipment and techniques.
