FAQs About This Product

What is 0.12mm FeCrAl (KA1) Round Wire?

KA1 is a type of wire made from an iron-chromium-aluminium alloy (FeCrAl) and is commonly used in heating elements and high-temperature applications. The wire has a diameter of 0.12mm, which is considered ultra-fine and can be used in a wide range of industrial and commercial applications due to its excellent resistance to oxidation and high-temperature strength.

KA1 wire has a high resistance to oxidation and corrosion at high temperatures and is commonly used in applications such as electric heating elements in home appliances, industrial furnaces, and heating elements in tobacco vaporizers. It is also used in the production of high-temperature resistance wire-wound resistors and in electronic cigarette coils.

KA1 wire is known for its high electrical resistance and good formability, it is also easy to work with and can be bent, twisted, and shaped without losing its resistance properties.

Additionally, 0.12mm wire can be used for jewellery making, such as for creating wire-wrapped pendants or earrings.

It is important to note that KA1 wire should be used only in dry environments, as it is not suitable for use in atmospheres containing chlorine or sulphur.

What are the Primary Uses of KA1 Wire?

KA1 round wire, also known as FeCrAl wire, is a type of wire made from an iron-chromium-aluminium alloy and is commonly used in heating elements and high-temperature applications. Some of the most common uses for KA1 round wire include:

1. Electric heating elements: used in the production of electric heating elements for home appliances, such as ovens, toasters, and hair dryers.
2. Industrial Furnaces: used in the production of heating elements for industrial furnaces, such as furnaces for heat treatment, annealing, and sintering.
3. Wire-wound resistors: used in the production of wire-wound resistors, which are used in electronic devices and equipment to control the flow of electricity.
4. Electric motors: used in the production of electric motors, such as those found in fans and pumps.
5. High temperature furnace: used in high-temperature furnace, such as in glass production, solar cell production, and more
6. Laboratory equipment: used in the production of heating elements for laboratory equipment such as heating mantles and ovens
7. Re-crystallization of semiconductors: used in the re-crystallization of semiconductors, which improves the quality and performance of the semiconductors.

It is important to note that KA1 round wire should be used only in dry environments, as it is not suitable for use in atmospheres containing chlorine or sulphur.

What Temperature Can KA1 Wire Withstand?

FeCrAl (often known by the brand name “Kanthal” or “KA1” for certain types) is an iron-chromium-aluminum alloy used primarily for its high resistance and excellent oxidative properties at elevated temperatures.

The maximum continuous operating temperature of FeCrAl (KA1) wire is typically up to 1400°C (2550°F). However, the exact temperature may vary based on the specific alloy composition, the application it’s used in, and the environmental conditions. Always refer to the manufacturer’s specifications and guidelines when determining the appropriate temperature range for a particular wire or application.

Is KA1 FeCrAl Wire Magnetic?

FeCrAl (KA1) wire is generally considered to be slightly magnetic, especially at room temperature. However, its magnetic properties decrease as it’s heated. When the wire is at or above certain temperatures, it exhibits reduced magnetic permeability, making it essentially non-magnetic at those elevated temperatures.

It’s worth noting that while FeCrAl has some magnetic properties at room temperature, it’s not as magnetic as regular iron or some stainless steel alloys. If magnetic properties are a concern for a specific application, it’s essential to test the wire under the relevant conditions or consult the manufacturer’s data.

Can KA1 FeCrAl Wire be Welded or Soldered?

Yes, KA1 (FeCrAl) wire can be both used for welding and soldering, but there are certain considerations to keep in mind:

Welding:

1. Welding FeCrAl: FeCrAl can be challenging to weld compared to some other materials due to its composition and properties. However, with the proper technique, it can be welded successfully.
2. Technique: Tungsten Inert Gas (TIG) welding is one of the most commonly used methods for welding FeCrAl.
3. Filler Material: When welding FeCrAl, it’s often best to use a matching filler material or one specifically designed for high-resistance alloys.
4. Preparation: Ensure the surfaces to be welded are clean and free from oxides or contaminants to achieve a solid weld.
5. Heat Management: Careful management of heat input during the welding process is essential to avoid damaging the alloy’s properties.

Soldering:

1. Oxide Layer: FeCrAl develops a stable oxide layer when heated. This oxide layer can make soldering challenging since solder does not readily wet or bond to oxidised surfaces.
2. Flux: Using an aggressive flux can help in breaking down the oxide layer and promoting better adhesion of the solder.
3. Solder Choice: High-temperature solders are typically used with FeCrAl because the alloy itself is used in high-temperature applications. Using a solder that melts at a lower temperature than the wire’s operating range is not advisable.
4. Preparation: As with welding, cleaning the wire before soldering can make the process more successful. Removing as much of the oxide layer as possible will help the solder bond.
