FeCrA1 Wire Ribbon

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

The FeCrAl wire ribbon, measuring 0.7mm x 0.05mm, is a highly versatile and efficient product crafted from an alloy of iron, chromium, and aluminum (KA1). A wide variety of industrial and commercial applications benefit from this wire ribbon’s exceptional resistance to oxidation and high temperatures. The FeCrAl wire ribbon ensures durability and longevity in high-stress applications by virtue of its robust composition.

Thermal stability is one of the primary benefits of this wire ribbon. Manufacturing processes that involve high heat require material that can withstand extreme temperatures without losing its structural integrity. In addition to industrial furnaces, toasters and hair dryers, it can also be used in the automotive industry for various heating applications. Aside from its resistance to oxidation, it can also operate reliably in corrosive environments, making it an excellent material for chemical processing.

Specification of this KA1 Ribbon Wire:

  • Diameter – 0.7mm x 0.05mm
  • Ohms/ft – 41.11

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

FAQs About This Wire

What Is The Lifespan Of FeCrAl Wire Ribbon Under Normal Usage?

The lifespan of a FeCrAl wire ribbon depends substantially on its application, environment, and operational parameters. The FeCrAl alloy, owing to its exceptional thermal stability and oxidation resistance, generally offers a greater lifetime than other heating elements.

FeCrAl wire ribbon can last several years under normal conditions. As a result of its high temperature tolerance and resistance to corrosive environments, it is durable. If the ribbon is not exposed to extreme mechanical stress or aggressive chemical environments, it can maintain its integrity and performance for a long time.

There are a number of factors that can affect the longevity of heating coils, including the frequency of heating cycles, the maximum temperature reached, and the presence of corrosive or abrasive substances. Maintaining and installing FeCrAl wire ribbon correctly is also crucial to maximising its lifespan. The FeCrAl wire ribbon can be extremely reliable and long-lasting in well-controlled environments with optimal use conditions.

Are There Any Limitations To Using FeCrAl Wire Ribbon?

  1. Temperature Limitation: While FeCrAl wire ribbon is designed for high-temperature applications, it does have an upper temperature limit. Exceeding this limit can lead to a reduction in the material’s lifespan and structural integrity.
  2. Flexibility and Handling: The wire ribbon, being thin and metallic, may have limitations in flexibility compared to some other materials. This can affect its usability in applications requiring significant bending or repeated flexing.
  3. Electrical Conductivity: FeCrAl wire ribbon has specific electrical resistance properties. It may not be suitable for applications that require either very low or very high electrical resistivity.
  4. Corrosive Environments: While it offers good resistance to oxidation, certain corrosive environments, especially those containing sulfur or certain other chemicals, can still affect its longevity and performance.
  5. Mechanical Stress: Under continuous mechanical stress or vibration, the FeCrAl wire ribbon might experience wear or fatigue faster than some other materials.
  6. Installation and Handling Complexity: Installing and handling FeCrAl wire ribbon requires a certain level of expertise and care. Incorrect handling or installation can lead to performance issues or reduced lifespan.
  7. Cost Considerations: Depending on the application and the quality of the ribbon, cost can be a factor when considering FeCrAl wire ribbon, especially in comparison to alternative materials.
