Resistance wire is a specialised type of wire designed to restrict the flow of electricity, generating heat as a result. Unlike standard electrical wiring, which aims to conduct electricity with minimal resistance, resistance wire is specifically engineered to create a controlled level of electrical resistance. This property makes it an essential material in heating elements, precision electronics, and industrial applications.
At The Crazy Wire Company, we supply a wide range of resistance wire suitable for various applications, including Nichrome, FeCrAl, and Stainless Steel wire.

What is Resistance Wire?
Resistance wire is typically made from metal alloys such as Nichrome (nickel-chromium), FeCrAl (iron-chromium-aluminium), and Stainless Steel. These materials are chosen for their ability to generate heat efficiently when an electric current passes through them.
Key Properties of Resistance Wire
High Electrical Resistance: Creates controlled heating in applications such as toasters, electric ovens, and industrial furnaces.
Heat Resistance: Can withstand high temperatures without degrading or melting.
Corrosion Resistance: Many resistance wires are designed to resist oxidation, extending their lifespan.
Durability: Resistant to wear and tear even at extreme temperatures.
Flexibility: Available in various diameters to suit different applications.
How Does Resistance Wire Work?
Resistance wire works on the principle of Ohm’s Law, which states that voltage (V) is equal to the current (I) multiplied by the resistance (R):
V = I X R
When an electric current passes through, it encounters resistance, causing the energy to be converted into heat. This heating effect is used in various industrial and household applications where controlled heat generation is essential.
Types of Resistance Wire
There are several types, each suited for different applications. Below is a comparison of the most common types:
| Wire Type | Composition | Maximum Temperature | Common Uses | Corrosion Resistance |
|---|---|---|---|---|
| Nichrome | Nickel-Chromium | ~1,400°C | Heating elements, foam cutters, e-cigarettes | Excellent |
| FeCrAl | Iron-Chromium-Aluminium | ~1,300°C | Industrial furnaces, kilns, electric heating | Very High |
| Stainless Steel | Iron-Chromium-Nickel | ~1,150°C | Electrical heating, resistors, precision circuits | High |
Choosing the Right Resistance Wire
For high-heat applications (furnaces, ovens) – FeCrAl wire is ideal.
For general heating elements (toasters, hairdryers) – Nichrome wire is the standard choice.
For electrical resistance applications – Stainless steel wire provides reliability and efficiency.
Common Applications
Resistance wire is widely used in industries and everyday applications. Below are some of the most common uses:
1. Heating Elements
Resistance wire is at the core of many heating devices, including:
Toasters and Hairdryers – The wire heats up to produce warmth efficiently.
Electric Ovens and Stovetops – Used in heating coils for consistent temperature control.
Industrial Furnaces and Kilns – Utilised in high-temperature manufacturing processes.
2. Electronic Components
In precision electronics, it is used in:
Resistors – Essential for regulating current flow in electrical circuits.
Thermocouples – Measures temperature in industrial applications.
Voltage Dividers – Helps distribute voltage efficiently in circuits.
3. Foam Cutting and Crafting
Thin resistance wire is commonly used in hot wire foam cutters, allowing for precision cutting in model-making and insulation projects.
4. Medical and Laboratory Equipment
Due to its ability to generate controlled heat, resistance wire is used in sterilisation equipment and lab testing devices.
