KA1 Ribbon Wire Spool

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

The KA1 Ribbon Wire Spool is a specialised product designed for various applications in the field of electronics and thermal projects. With dimensions of 0.2mm x 0.8mm, FeCrAl A1 wire is highly durable and resistant to oxidation, so it is a great choice for projects that require extended life and stability under high temperatures. In addition to its excellent electrical resistance and superior heat resistance, FeCrAl A1 alloy, also known as KA1, is ideal for applications such as electric heating elements in high-temperature furnaces, ceramics, glass, steel, and electronics.

With its ribbon-like shape, this KA1 Ribbon Wire Spool offers increased surface area and improved efficiency. This makes it ideal for small-scale resistance units, hobbyist projects, and specialised industrial equipment. The thin, yet robust structure of the wire allows for precise control of resistance, which is essential for applications requiring precise power regulation. In addition, its flexibility and ease of handling make it an ideal choice for designs requiring intricate details and compact assemblies.

Specification of this KA1 Ribbon Wire Spool:

  • Diameter – 0.2mm x 0.8mm
  • Ohms/ft – 8.85

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

FAQs About This Wire

How Does The KA1 Ribbon Wire Spool Resist Oxidation?

The KA1 Ribbon Wire Spool resists oxidation due to the properties of its material composition, primarily FeCrAl (Iron-Chromium-Aluminum) alloy, also known as KA1. Specifically designed for high-temperature resistance and stability, this alloy is resistant to corrosion. When exposed to heat, chromium in the alloy forms a protective oxide layer on the surface of the wire. Essentially, the oxide layer acts as a barrier, keeping the metal below from further corrosion and oxidation. A material with this characteristic is particularly appropriate for applications involving prolonged exposure to high temperatures, where other materials might degrade or oxidise more rapidly. In many industrial and electrical applications, the stability of the oxide layer under thermal stress contributes greatly to long-term reliability and durability.

How Durable Is KA1 Ribbon Wire Spool In Long-Term Applications?

  1. Heat Resistance: The FeCrAl A1 alloy can withstand high temperatures without degrading, making it ideal for applications involving continuous or intermittent heating.
  2. Oxidation Resistance: As the wire heats, a protective oxide layer forms on the surface, shielding the metal from further oxidation and prolonging its lifespan.
  3. Mechanical Stability: The alloy maintains its structural integrity under thermal cycling, resisting warping or brittleness. This can occur in other materials under similar conditions.
  4. Corrosion Resistance: Apart from resisting oxidation, the wire is also less prone to corrosion from environmental factors. This ensures that it remains effective in various settings.
  5. Consistent Performance: The wire’s ribbon shape allows for uniform heating and cooling, reducing the likelihood of hotspots that can lead to premature failure.
  6. Flexibility and Tensile Strength: Despite its thin dimensions, the KA1 Ribbon Wire Spool is designed to be flexible yet strong. This is to avoid breaking or fractures during use and handling.
