FeCrAl Heating Wire

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

The 0.23mm (31 AWG) KA1 FeCrAl heating wire is a versatile and durable product designed for various heating applications. As a blend of iron, chromium, and aluminum (FeCrAl), this wire is known for its high temperature resistance and resistance to oxidation. It provides a perfect balance of flexibility and strength, facilitating easy handling and installation in various environments.

Industrial furnaces, household appliances, like toasters and hair dryers, and laboratory equipment requiring precise temperature control can benefit from this FeCrAl heating wire. A high electrical resistance and stability at elevated temperatures ensure efficient energy use, reducing costs and increasing efficiency. Its resistance to sulfur and other corrosive elements also prolongs its lifespan, reducing the need for frequent replacements. Its uniform heat distribution makes it ideal for ceramics and metal processing applications requiring consistent heat distribution. Additionally, its compatibility with a variety of insulation materials allows for customising its use to suit a variety of applications.

Specification of this FeCrAl Wire:

  • Diameter – 0.23mm (230 Micron – 31 AWG)
  • Ohms/ft – 34.36

We also offer the KA1 grade as flat wire too if required.

FAQs About This Wire

What Are The Maintenance Requirements For FeCrAl Heating Wire?

  1. Regular Inspection: Periodically check the wire for any signs of wear, damage, or oxidation. Even though FeCrAl wire is resistant to oxidation, it’s important to monitor its condition, especially in harsh environments.
  2. Cleaning: Keep the wire clean from any debris or buildup that might occur during use. If necessary, gently clean the wire with a soft, dry cloth. Avoid using harsh chemicals or abrasives, as they may damage the wire’s surface.
  3. Proper Storage: When not in use, store the FeCrAl heating wire in a dry, cool place away from corrosive substances and extreme temperatures to prevent any premature degradation.
  4. Avoiding Mechanical Stress: Although the wire is flexible, avoid excessive bending or twisting, which can cause mechanical stress and potentially lead to fractures or breaks over time.
  5. Electrical Testing: For applications where the electrical properties are critical, periodically test the wire’s resistance to ensure it maintains its specified electrical characteristics.
  6. Temperature Monitoring: If possible, monitor the operational temperature during use to ensure the wire is not being overheated beyond its specified maximum temperature limit.

What Is The Lifespan Of FeCrAl Heating Wire In Continuous Use?

The lifespan of FeCrAl heating wire depends on a number of factors, including the operational temperature, environmental conditions, and the particular application. It is generally known for its durability, as FeCrAl wire resists high temperatures and corrosion, which leads to a longer lifespan. High temperatures can shorten the wire’s lifespan, while low temperatures can extend it. The temperature at which the wire operates directly affects its longevity. Corrosive substances, high humidity, or fluctuating temperatures are also important environmental factors. The lifespan is further impacted by the quality of installation and usage. Proper handling and avoiding mechanical stress can minimise premature wear.

The wire’s operational life can be extended by regular maintenance, including routine inspections and cleanings. FeCrAl heating wire has a long lifespan under ideal conditions, although this can vary considerably based on the factors mentioned above. To determine life expectancy with accuracy, it is recommended that you consult the manufacturer’s specifications, which provide detailed data based upon extensive testing.
