Flat FeCrAl Ribbon Wire

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

The 0.8mm x 0.05mm KA1 Flat FeCrAl Ribbon Wire is a versatile and high-quality product, designed to meet the diverse needs of various industries. This flat FeCrAl ribbon wire is made of a KA1 alloy that is known for its superior heat resistance and durability. Flat wires, measuring 0.8mm in width and 0.05mm in thickness, have a greater surface area than traditional round wires, allowing for better heat distribution. As a result, it is a great choice for applications requiring precise temperature control and consistent performance.

Flat FeCrAl ribbon wire is used in electronic components because of its high temperature stability and resistance to oxidation. As a result of its ability to resist prolonged exposure to high temperatures, it is extensively used for the manufacture of heating elements. In the aerospace industry, this wire is valued for its corrosion resistance and reliability. In addition, its strengths make it ideal for use in laboratory equipment requiring precision and durability.

Specification of this Flat FeCrAl Ribbon Wire:

  • Diameter – 0.8mm x 0.05mm
  • Ohms/ft – 34.63

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

FAQs About This Wire

How Does Environmental Exposure Affect This Wire?

  1. Temperature Variations: This wire is designed to withstand high temperatures, but extreme or rapid temperature changes can impact its structural integrity over time. Prolonged exposure to high temperatures may cause gradual changes in its properties, such as thermal expansion or changes in resistance.
  2. Humidity and Moisture: While FeCrAl alloys generally have good corrosion resistance, prolonged exposure to high humidity or moisture can lead to oxidation or corrosion, especially at elevated temperatures. This can affect the wire’s performance and lifespan.
  3. Corrosive Environments: In environments with corrosive elements, such as certain chemicals or saltwater, the wire may experience accelerated wear. KA1 has decent resistance to oxidation and corrosion, but harsh chemicals can still impact its durability.
  4. Mechanical Stress: Environmental factors like wind or vibration can exert mechanical stress on the wire, potentially causing fatigue over time. While the wire is made to be durable, repeated mechanical stress can lead to wear and tear.

How To Properly Dispose Of Used KA1 Flat FeCrAl Ribbon Wire?

The proper disposal of used KA1 Flat FeCrAl Ribbon Wire is crucial for environmental safety and compliance with waste management regulations. Wire should not be disposed of in regular household waste as it is a specialised industrial material. You should treat it instead as electronic or industrial waste, depending on your local regulations. Metals and alloys should be disposed of properly by contacting local waste management or recycling authorities. There may be facilities for recycling or safely disposing of such materials in some regions. In addition, it’s always a good idea to find out if any companies that recycle industrial or electronic waste can handle this type of waste.

Certain components of the wire may be recovered for recycling at these facilities, reducing their environmental impact. Additionally, if the wire is contaminated with hazardous substances, it may require special handling as hazardous waste. Be sure to store wire safely until it is disposed of or recycled, so that there is no risk of contamination or hazards to the environment. Using these guidelines can help make waste management more responsible and sustainable.
