Bare Copper Annealed FeCrAl Wire For Temperature Applications Rated to 1400.C Operating Temperature

Our bare copper annealed FeCrAl wire, rated for 1400°C operating temperatures, is a total beast for high-temperature industrial applications, and we’re pumped to share why it’s such a killer choice. This iron-chromium-aluminum alloy is designed to deliver rock-solid performance in the hottest, toughest environments, from furnaces to high-temp sensors.

This FeCrAl wire, typically with 20-25% chromium and 5-6% aluminum (like 0Cr25Al5 or Kanthal A-1), is built to handle extreme heat up to 1400°C, making it perfect for industrial heating elements, kilns, or temperature sensors. The annealing process softens the wire, boosting its formability so we can shape it into tight coils or custom designs without cracking—ideal for precision applications. Its oxidation resistance is next-level, forming a protective Al2O3 oxide layer above 1000°C that shields it from degradation in sulfur-rich or acidic atmospheres.

With an electrical resistivity of 1.35-1.45 µΩ·m, this wire generates heat super efficiently, ensuring consistent performance in high-temperature setups. Its corrosion resistance is top-notch, standing up to harsh chemical or metallurgical environments. The tensile strength (~550-600 MPa post-annealing) keeps it durable, and its thermal conductivity (~11-13 W/mK) ensures steady heat distribution. The bare copper-like finish (due to annealing) gives it a clean look while maintaining functionality, and we can supply it in various gauges for any application.

The industry in 2025 is all about durability and sustainability, and our FeCrAl wire is right on trend. There’s a huge demand for high-temperature, corrosion-resistant materials in aerospace, automotive, and energy sectors, like EV battery systems, turbine parts, or ceramic firing kilns. Being 100% recyclable, it’s a great fit for eco-friendly manufacturing. As high-temperature automation and precision heating keep trending, this wire’s annealed flexibility and heat stability make it a top pick for cutting-edge designs.

Sure, Nichrome Cr20Ni80 is a bit more formable and great for lower-temperature applications, but our FeCrAl wire’s higher heat tolerance and oxidation resistance make it the champ for extreme environments. Stainless Steel 316 is corrosion-resistant but can’t match FeCrAl’s high-temperature performance or resistivity. Just watch out for creep at max temps, though this wire handles most industrial conditions like a pro.

From high-temp sensors to industrial furnaces, our bare copper annealed FeCrAl wire delivers the heat resistance, reliability, and efficiency that keep high-temperature applications running strong.

Product Description:

FeCrAl Wire is available in different surface finishes including bright, oxided, and acid. The bright steel FeCrAl Wire has a shiny, reflective surface that is smooth to the touch. The oxided FeCrAl Wire, on the other hand, has a dark and rough surface that has been treated with an oxidizing agent. The acid FeCrAl Wire has a surface that has been treated with acid to remove any impurities or contaminants. This type of surface finish is ideal for applications that require a clean and hygienic environment.

The FeCrAl Wire has an elongation of at least 12% and a tensile strength of at least 650 MPa. These properties make the wire strong and durable, with the ability to withstand high levels of stress and pressure. The annealed FeCrAl Wire is soft and malleable, making it easy to work with and shape into different forms. This type of wire is ideal for applications that require flexibility and ease of use.

The hard or soft FeCrAl Wire is available in different conditions, depending on the specific application. The hard wire is more rigid and durable, making it suitable for use in heavy-duty applications that require high levels of strength and resilience. The soft wire, on the other hand, is more flexible and malleable, making it ideal for use in applications that require a greater degree of flexibility and ease of use.

In summary, the FeCrAl Wire is a versatile and durable wire that is ideal for use in high-temperature applications. It is available in different conditions and surface finishes, making it suitable for a wide range of applications. The bright steel FeCrAl Wire, annealed FeCrAl Wire, and hard or soft FeCrAl Wire are all excellent options depending on the specific needs of the application.

Applications:

FeCrAl Wire is an excellent product for use in heating elements, as its high resistance and low temperature coefficient make it an ideal choice for applications where consistent and precise heating is required. It can also be used in the production of copper clad steel wire, providing an alternative to traditional copper wire that is more cost-effective and durable.

Annealed FeCrAl Wire is another variant of DLX FeCrAl Wire that is softer and more malleable than its hard counterpart. This product is commonly used in the construction industry, particularly for the production of black annealed tie wire. Annealed FeCrAl Wire is easy to work with and can be cut, bent, and shaped to suit a variety of applications.

DLX FeCrAl Wire is a reliable and efficient product that can be used in a range of scenarios. Its versatility and durability make it an ideal choice for industries such as construction, heating and ventilation, and electrical engineering. Whether you need a hard or soft wire, packed on spools or in coils, DLX FeCrAl Wire is the product for you.
