KA1 Kanthal

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 1.15mm (17 AWG) KA1 (FeCrAl A1) variety, is a high-quality, versatile product known for its exceptional performance in a wide range of applications. An alloy of iron, chromium, and aluminum, Kanthal wire has a greater heat resistance, durability, and longevity than standard wires. Providing the best balance between flexibility and strength, the 1.15mm diameter is ideal for intricate designs and demanding applications. The heating element’s ability to withstand temperatures up to 1400°C makes it an excellent choice for industrial furnaces, household appliances like toasters and hair dryers, and laboratory equipment.

The electrical resistance properties of Kanthal wire are particularly noteworthy, as they provide consistent performance and reliability over time. This makes it a popular material for resistors and heating coils in electronic and electrical equipment.

Furthermore, its resistance to oxidation and corrosion extends its lifespan, ensuring long-term use with minimal maintenance. It is commonly used by hobbyists and DIY enthusiasts for creating custom heating elements, experimental projects, and art installations requiring a durable, heat-resistant wire.

Specification of this Kanthal Wire:

  • Diameter – 1.15mm (1150 Micron – 17 AWG)
  • Ohms/ft – 1.35

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

FAQs About This Wire

Is Kanthal Wire Suitable For Artistic Projects?

Yes, Kanthal wire can be used for artistic purposes. As a versatile material, its unique combination of flexibility, strength, and heat resistance makes it a favorite among artists and craftspeople alike. Many artists use Kanthal wire in sculptural and jewelry making, and in other creative endeavors requiring a durable, malleable material. Having the ability to withstand high temperatures allows this material to be used in projects that require heat treatment or firing. As a result of Kanthal wire’s resistance to oxidation, art pieces are guaranteed to retain their appearance and integrity for a long time, making it an excellent choice for both indoor and outdoor uses.

What Makes Kanthal Wire Resistant To Oxidation?

Kanthal wire’s resistance to oxidation primarily stems from its unique composition. It is made from a specialised alloy of iron (Fe), chromium (Cr), and aluminum (Al), known as FeCrAl. The chromium in the alloy forms a protective oxide layer on the surface of the wire when exposed to air, especially at high temperatures. This oxide layer acts as a barrier, protecting the underlying metal from further oxidation and corrosion. The aluminum content in the alloy further enhances this protective layer, making it more stable and effective at higher temperatures. This combination of chromium and aluminum in the alloy gives Kanthal wire its excellent oxidation resistance, enabling it to maintain its integrity and performance in challenging environments, such as in high-temperature applications or in settings with fluctuating air quality.
