KA1 Kanthal Wire

This wire source directly from Kanthal. It was originally produced and trademarked by the Swedish company Kanthal, now a part of the Sandvik Group, and was specifically designed to withstand extreme temperatures, making it ideal for electrical heating elements.

Kanthal wire, specifically the 1.02mm (18 AWG) KA1 (FeCrAl A1) type, is a high-quality alloy wire known for its exceptional durability and resistance to oxidation at high temperatures. Iron, chromium, and aluminum are the main constituents of this wire, so it has a higher melting point than many other metals. Flexibility and strength are balanced with its 1.02mm thickness, making it a versatile and versatile choice for a wide range of uses. Kanthal wire is particularly useful for electronic components, industrial heating elements, and household appliances that require high-temperature resistance.

As an electronic component, it’s used in resistors and heating coils due to its stable resistance properties. Often used in furnaces and kilns in industrial settings, this wire can withstand prolonged exposure to extreme heat without degrading. The material is commonly used in toasters, ovens, and hair dryers, providing efficient heating and ensuring safety. Its resistance to sulfur and other corrosive compounds further increases its applicability in such environments. Its ease of use and compatibility with standard tools make it a popular choice for DIY enthusiasts and professionals alike.

Specification of this Kanthal Wire:

  • Diameter – 1.02mm (1020 Micron – 18 AWG)
  • Ohms/ft – 1.77

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

FAQs About This Wire

Can Kanthal Wire Be Recycled Or Reused?

The condition of Kanthal wire and its intended use will determine whether it can be recycled or reused. In addition to being primarily composed of iron, chromium, and aluminum, Kanthal can also be recycled like many other metal alloys. During the recycling process, Kanthal wire is melted down and reformatted, which is carried out by specialised recycling facilities.

As far as reuse is concerned, if the wire is not significantly damaged or degraded, it can be repurposed for the same or a different purpose. It is, however, important to assess the wire’s integrity before reusing it, especially if the wire has been exposed to high temperatures or corrosive environments. It is important that the wire’s structural and resistance properties remain intact in order to ensure its safety and efficiency within the end use application.

What Is The Melting Point Of Kanthal Wire?

Kanthal wire, known for its high resistance to heat, has a melting point that is significantly higher than many other metals. The melting point of Kanthal wire, which is a blend of iron, chromium, and aluminum (FeCrAl), is approximately 1500°C (2732°F). This high melting point is one of the key features that makes Kanthal wire suitable for use in high-temperature applications, such as in industrial heating elements, electrical resistors, and household appliances like toasters and ovens. The wire maintains its structural integrity and resistance properties even at elevated temperatures, making it a reliable choice for these applications.
