Description

KA1 Metal Round Wire

The Crazy Wire Company are best known and long established as Europe’s preferred suppliers of top quality KA1 metal round wire. We have enormous stock levels at all times as we use this wire to weave our mesh products.

0.07mm FeCrAl metal round wire is a type of electric resistance wire that is made from an iron-chromium-aluminum alloy. This type of wire is known for its high-temperature resistance and good oxidation resistance, making it suitable for use in high-temperature heating applications.

The wire has a round cross-section with a diameter of 0.07mm, which is relatively thin and suitable for use in applications that require fine, precise heating. It is commonly used in heating elements for household appliances, industrial furnaces, and other high-temperature applications where reliability and durability are critical.

FAQs About This Wire

Is A Higher Or Lower Resistance Wire Able To Heat Up More?

The ability of a wire to heat up is directly proportional to its electrical resistance. A higher resistance wire will heat up more than a lower resistance wire under the same electrical conditions.
When an electrical current flows through a wire, some of the energy in the current is converted into heat due to the resistance of the wire. The amount of heat generated is proportional to the square of the current and the resistance of the wire. So, a wire with higher resistance will generate more heat when the same current flows through it as compared to a wire with lower resistance.
It’s important to note that the wire’s ability to heat up also depends on other factors such as its thermal conductivity, which determines how well it can dissipate the heat generated, and its heat capacity, which determines how much heat it can store before its temperature increases.

Is An Electric Wire Affected By Temperature?

Yes, electric wires are affected by temperature. The electrical resistance of a wire changes with temperature, and this can impact the performance of the wire. As the temperature of a wire increases, its resistance also increases, and this can result in a reduction in the flow of current through the wire.

Additionally, temperature can also affect the mechanical properties of a wire, such as its tensile strength and ductility. Changes in temperature can cause the wire to expand or contract, which can result in mechanical stress and potentially cause the wire to fail.

In high-temperature applications, such as in electrical motors or power transformers, special materials are used that have a low temperature coefficient of resistance and are able to withstand high temperatures without failing.

Can I Use KA1 Wire As A Heating Element?

Yes, KA1 wire is commonly used as a heating element in a variety of applications, including industrial furnaces, electric heaters, and electronic cigarettes. The high resistance of KA1 wire, combined with its ability to withstand high temperatures, makes it well suited for use as a heating element.

KA1 wire is made of an iron-chromium-Aluminium (FeCrAl) alloy, which has a high melting point and excellent resistance to oxidation and corrosion. This makes it a durable and long-lasting heating element that can perform well in a wide range of environments.

Why Can’t Heating Elements Shock You?

Heating elements can potentially shock you if they are not used or installed properly, or if they are damaged or faulty. However, in general, heating elements are designed to be electrically insulated and isolated from the surrounding environment, and are not intended to come into contact with people or other conductive materials.

In most cases, heating elements are enclosed within a protective housing or sheath made of non-conductive material such as ceramic or metal, which helps to prevent accidental contact and reduce the risk of electrical shock. In addition, heating elements are often connected to a control circuit or thermostat that regulates the flow of electricity and helps to prevent overheating or other dangerous conditions.

However, it is important to remember that any electrical device or component can potentially be dangerous if it is not handled or used properly. If you are working with a heating element or any other electrical device, it is important to take appropriate safety precautions, such as wearing protective gear, following manufacturer instructions and safety guidelines, and seeking professional help if you are unsure or inexperienced.
