Nickel Chrome 80 Flat Wire

The Crazy Wire Company are best know as suppliers of top quality nickel chrome 80 flat 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 flat 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.

The nickel chrome 80 flat wire, measuring 21 AWG and with dimensions of 0.91mm x 0.45mm, is a highly versatile and reliable material suited for various applications. Nickel-chromium alloys are known for their extraordinary resistance to oxidation and corrosion, making them ideal for high-temperature applications. Using the flat profile of the wire ensures efficient heat distribution, which is necessary for applications such as electric heaters in industrial furnaces and household appliances like hair dryers and toasters.

Nickel chrome 80 flat wires have robust thermal properties, making them perfect for laboratory equipment requiring consistent heating elements. Its resistance to thermal expansion and stability in fluctuating temperatures contribute to its long life and reliability in these environments. Moreover, this wire is used in the automotive industry, most particularly in exhaust systems, where materials are required to withstand extreme heat and corrosion.

FAQs About This Wire

What Are The Thermal Properties Of Nickel Chrome 80 Flat Wire?

  1. High Melting Point: Nickel chrome 80 flat wire has a very high melting point, allowing it to maintain structural integrity and performance at elevated temperatures. This makes it suitable for use in environments where high heat is a constant factor.
  2. Thermal Conductivity: While not as high in thermal conductivity as some pure metals, this alloy still conducts heat effectively, ensuring uniform heat distribution along the length of the wire. This uniformity is crucial in applications like heating elements where consistent temperature is key.
  3. Thermal Expansion: The wire exhibits minimal thermal expansion, meaning it retains its shape and size under temperature variations. This stability is important in precision applications where dimensional consistency is vital.
  4. Resistance to Oxidation at High Temperatures: One of the standout features of nickel chrome 80 flat wire is its ability to resist oxidation even at high temperatures. This resistance ensures that the wire does not degrade quickly, prolonging its life and maintaining its efficiency.
  5. Heat Resistance: The wire is designed to withstand continuous exposure to high temperatures without losing its mechanical properties or suffering damage. This heat resistance is essential for use in heating elements and industrial applications.

Is Nickel Chrome 80 Flat Wire Easy To Install?

Flat Nickel Chrome 80 wire is easy to install because of its balance between flexibility and strength. Its flat profile facilitates alignment and fixation on multiple surfaces, making it a good choice for diverse applications due to its benefits. The wire’s specifications of 0.91mm x 0.45mm offer an ideal balance between bulk and thinness, so that delicate installations can be installed safely and robust applications can be carried out with ease. It is unlikely that specialised equipment will be needed when handling or installing this wire, as standard wire handling tools are typically enough. Due to this feature, it can be used for both DIY projects as well as professional installations. Safety protocols are particularly important when there is a risk of high temperatures or electrical currents. It may be necessary to seek professional guidance for more complex installations, particularly in specialised industrial environments.
