FeCrAl Alloy Round Wire

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

The 0.27mm (30 AWG) KA1 FeCrAl Alloy Round Wire is a versatile and high-quality product that caters to a wide range of applications in various industries. It is made of FeCrAl (Iron-Chromium-Aluminum) alloy, which provides incredible durability, resistance to oxidation and high temperature resistance. As a result of the 0.27mm diameter, equivalent to 30 American Wire Gauge (AWG), this wire is ideal for precision work because it strikes a balance between flexibility and strength. FeCrAl alloy round wire’s high electrical resistivity makes it a preferred choice for resistors and heating elements because of its high electrical resistance. As a result of its ability to withstand extreme temperatures without rapidly degrading, it is highly sought after in applications that require prolonged exposure to heat, including industrial furnaces and household appliances like toasters and hair dryers.

Specification of this KA1 FeCrAl Wire:

  • Diameter – 0.27mm (270 Micron – 30 AWG)
  • Ohms/ft – 24.86

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

FAQs About This Wire

Are There Any Special Tools Required For Working With FeCrAl Alloy Round Wire?

  1. Wire Cutters: To cut the wire to the desired length.
  2. Pliers: Useful for bending and shaping the wire.
  3. Wire Strippers: If insulation removal is needed, though this may not be applicable for bare FeCrAl wires.
  4. Safety Equipment: Gloves and eye protection are recommended, especially when cutting or bending the wire.

How Should KA1 FeCrAl Alloy Round Wire Be Stored?

  1. Dry Environment: Store the wire in a dry place to prevent any potential corrosion, even though KA1 FeCrAl alloy has good corrosion resistance.
  2. Room Temperature: Keeping the wire at room temperature is ideal. Extreme temperatures, particularly heat, can affect the wire’s properties over time.
  3. Avoid Direct Sunlight: Prolonged exposure to UV rays from sunlight can degrade the wire’s surface over time.
  4. Proper Coiling: The wire should be coiled neatly to prevent kinks or bends that could damage its structural integrity.
  5. Dust-Free Area: Store in a dust-free environment to prevent the accumulation of particles that could adhere to the wire, potentially affecting its performance in sensitive applications.
  6. Chemical-Free Zone: Keep the wire away from harsh chemicals or environments where corrosive substances are present.
  7. Physical Protection: If possible, store the wire in a container or a reel that provides physical protection, especially for thinner gauges that are more prone to damage.
  8. Label and Organise: Properly label the wire, especially if you are storing different types or gauges, to ensure easy identification and to prevent mix-ups.
