18AWG Nichrome Resistance Wire

The Crazy Wire Company are best known as suppliers of top quality 18AWG nichrome resistance heating wire. We have enormous stock levels at all times, as we use this wire to weave our high-specification woven mesh products. Our brilliant staff are experts in producing our spools of round wire on our 6 rapid action winding machines. All spools are produced to carry a little extra length to make up for any waste when handling the product.

The 1mm (18AWG) Ni80 Nichrome resistance wire is a precision-engineered product, blending nickel and chromium to create a material that is both durable and heat-resistant. With its rapid ramp-up time, this 18AWG wire is perfect for applications that require rapid temperatures and temperature consistency. The wire is resistant to oxidation, which not only enhances its lifespan but also reduces its maintenance needs significantly compared to other wire types.

Most commonly used in electronics, this wire is an excellent choice for constructing heating elements in household appliances, including toasters and hairdryers. Industrial applications of its stability and robust performance have included furnace heaters and kiln elements, among other things. As a result of the wire’s inherent malleability, it is suitable for detailed projects, catering to artisans seeking precision. The aerospace sector, which places a high value on resilience and dependability, also benefits from its consistent performance.

FAQs About This Wire

Yes, you can cut 18 AWG wire using a variety of tools, including wire cutters, wire strippers, or pliers. When cutting 18 AWG wire, it is important to use a tool that is designed for the specific size and type of wire, as well as one that is in good condition. This will help ensure that the wire is cut cleanly and without damaging the conductors inside.

When cutting wire, it is also important to take safety precautions, such as wearing gloves and protective eyewear, to protect yourself from cuts and scrapes. Additionally, it is important to make sure that the wire is properly supported during the cutting process to prevent it from snapping or fraying.

For most applications, it is recommended to use a wire cutter that is specifically designed for cutting 18 AWG wire, as this will help ensure clean, precise cuts every time. Some wire cutters may also have features that make it easier to hold the wire in place during the cutting process, such as a clamp or a locking mechanism.

What Is The True Value For Resistivity Of Nichrome Wire?

The resistivity of 18awg nichrome wire depends on several factors, including the specific composition of the wire and the temperature. The resistivity of nichrome is usually expressed in units of ohm-meters (Ω-m) and can range from about 1.0 Ω-m to 1.5 Ω-m.

It is important to note that the resistivity of nichrome wire is not a fixed value, but rather a value that changes with temperature. As the temperature of the nichrome wire increases, its resistivity will also increase. This temperature dependence of resistivity is an important consideration when using nichrome wire as a heating element, as it can affect the wire’s performance and stability.

In order to determine the exact resistivity of a particular nichrome wire, it is necessary to perform tests and measurements under specific conditions, such as temperature, composition, and wire diameter. These tests can be performed using specialized equipment and should be performed by experienced technicians in a controlled laboratory environment.

What Can Be Used Instead Of Nichrome Wire?

There are several alternatives to nichrome wire that can be used for heating elements and similar applications, including:

  1. KA1 wire: KA1 wire is a type of iron-chromium-aluminium (FeCrAl) alloy that is often used as a substitute for nichrome wire. It has a similar resistivity to nichrome and is widely used in applications such as heating elements, electric stoves, and hot plates.
  2. Stainless steel wire: Stainless steel wire, particularly type 304 or type 316, is another alternative to nichrome wire. Although it has a higher resistivity than nichrome, it is more corrosion-resistant and can be used in damp or corrosive environments.
  3. Copper wire: Copper wire is a widely used electrical conductor that has a lower resistivity than nichrome. Although it is not as good a conductor as nichrome, it is often used in applications that require lower resistance heating elements, such as electric stoves or hot plates.
  4. Molybdenum disilicide (MoSi2) wire: MoSi2 wire is a refractory metal that is widely used in high-temperature applications. It has a high melting point and a relatively low resistivity, making it a good alternative to Nichrome for applications that require high-temperature heating elements.

Is Nichrome Wire Aluminium?

No, nichrome wire is not made of aluminium. nichrome wire is an alloy made of nickel (Ni) and chromium (Cr), with some other elements added in smaller quantities to improve its performance. The exact composition of nichrome wire may vary depending on the manufacturer and the specific application, but nickel and chromium are the two primary elements that make up the majority of the wire. The combination of these two elements gives nichrome its high resistance, high temperature resistance, and good stability, making it well-suited for use in heating elements, electrical resistors, and other applications.
