Description

FeCrAl Resistance Wire

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

Our delightful staff are experts in producing our spools of round wire on our 6 rapid action winding machines in which all spools are produced to carry a little extra length to make up for any waste when handling the product.

We specialise in fulfilling high volumes of smaller wire spools to suit every requirement and budget however our master spools weigh between 1kg and 15kgs, so please contact us if you require a larger quantity – sales@wireandstuff.co.uk.

Because we produce our own spools, we are able to offer a wide choice of AWG and lengths and also guarantee the best prices in Europe.

FAQS About This Wire

What Is The Calculation To Work Out The Resistance Of A Wire?

The resistance of a wire can be calculated using Ohm’s law, which states that the resistance of a conductor is directly proportional to its length and inversely proportional to its cross-sectional area. The formula for resistance is:

R = ρ * L / A

Where:

  • R is the resistance (in ohms)
  • ρ is the resistivity of the material (in ohm-meters)
  • L is the length of the wire (in meters)
  • A is the cross-sectional area of the wire (in square meters)

What Are The Uses For KA1 Resistance Wire?

0.45mm KA1 wire is a type of iron-chromium-aluminium (FeCrAl) alloy wire with a diameter of 0.45mm. It is commonly used as a resistance heating wire in a high-temperature heating element in industrial processes. It is known for its high resistance to oxidation and corrosion and its ability to retain its strength at high temperatures. The resistance of this wire can be calculated using Ohm’s law and the wire’s specific resistivity, which can be found in product specifications.

0.45mm KA1 wire is used for several applications, including:

  1. Industrial heating elements: In high-temperature heating elements, such as furnace heating elements, in industrial processes.
  2. Temperature sensors: In high-temperature electrical heating elements, used as resistance wire in temperature sensors.
  3. Laboratory equipment: In some laboratory equipment, as a heating element for high-temperature experiments.
  4. High-temperature electrical applications: In high-temperature electrical applications where resistance, stability, and resistance to oxidation are important factors.
