Flat KA1 Ribbon Wire

The Crazy Wire Company are best known and long established as Europe’s preferred suppliers of top quality flat KA1 ribbon wire and we also have enormous stock levels at all times as we use this wire to weave our mesh products.

The flat KA1 ribbon wire, measuring 0.8mm x 0.08mm and made of FeCrAl A1, is a versatile and reliable component widely used in various applications. In environments where corrosion and oxidation are concerns, this product offers excellent durability and resistance. The flat ribbon shape maximises the surface area, allowing for better heat dissipation than traditional round wires, making it especially useful for temperature-sensitive applications. As a result, the heating pattern remains uniform, ensuring a consistent performance.

As a result of its high-temperature resistance, KA1 ribbon wire is commonly used in electronic and electrical projects. Industrial furnaces and kilns benefit from its consistent performance under high heat conditions. Also, the wire’s flexibility and strength make it ideal for making custom heating coils that are tailored to specific needs.

Specification of this Flat KA1 Ribbon Wire:

  • Diameter – 0.8mm x 0.08mm
  • Ohms/ft – 22.24

We also offer more of this KA1 wire too if required.

FAQs About This Wire

What Is The Lifespan Of Flat KA1 Ribbon Wire?

The lifespan of flat KA1 ribbon wire depends on several factors, including the operating environment, temperature, mechanical stress, and frequency of use. The flat KA1 ribbon wire can generally last for several years when used under optimal conditions, including away from excessive corrosion, extreme temperatures, and mechanical strain. This product’s FeCrAl A1 composition provides excellent resistance to oxidation and corrosion, allowing it to live for a very long time, especially in controlled environments. A regular maintenance program and proper handling can also extend its lifespan. A more accurate estimate can be obtained by consulting technical specifications or seeking expert advice, depending on the application and environment.

What Are The Electrical Properties Of Flat KA1 Ribbon Wire?

  1. Resistivity: KA1, a type of FeCrAl alloy, typically has a high electrical resistivity, making it efficient for use in heating elements where controlled resistance is crucial.
  2. Temperature Coefficient of Resistance: This wire has a relatively stable resistance across a wide temperature range, ensuring consistent performance even under varying thermal conditions.
  3. Conductivity: While not as conductive as metals like copper or aluminum, the conductivity of flat KA1 ribbon wire is adequate for applications requiring moderate electrical current.
  4. Durability under Electrical Stress: The FeCrAl A1 composition offers good performance under electrical stress, making the wire durable and reliable for long-term use.
  5. Heat Generation: Its ability to generate heat when an electrical current passes through, due to its resistance, is particularly beneficial in applications like heating elements and resistors.
