Nichrome Wire Calculator

nichrome wire

Nichrome, an alloy composed of Nickel and Chromium, possesses remarkable resistance to corrosion and boasts a high melting point. These properties make it a preferred choice for various electrical appliances and tools.

There are two types of Nichrome heater wire :

Nichrome A is composed of 80% nickel and 20% chromium NiCr alloy. It has a lower temperature coefficient of resistance in comparison to Nichrome C. Nichrome A can operate at a service temperature up to 1150℃ or 2100°F.

Nichrome C contains 60% nickel, 16% chromium, and the remaining 24% iron NiCr alloy. It has a high coefficient of electric resistance as compared to Nichrome A and can operate at a service temperature up to 1000℃ or 1850°F.

By winding Nichrome into coils with specific electrical resistance, heat can be generated by passing current through it. Simplify your calculations with our online Nichrome wire calculator, which allows you to effortlessly determine the resistance, power, current, and voltage of your Nichrome coil. Just input the length, thickness (between 10 to 40 Gauge), and temperature (between 205 to 1000℃) of the NiCr to attain, and get instant results.

Nichrome wire is a perfect material for heating elements and other applications because of the following qualities: 

High temperature resistance: Nichrome wire is resistant to degradation and loss of structural integrity even at very high temperatures. 

Oxidation resistance: Because nichrome wire resists oxidation, it will not rust or corrode readily. 

Low resistivity: Because nichrome wire has a low resistance, it is an effective electrical conductor. 

High strength: Because nichrome wire is robust and long-lasting, it can withstand mechanical stress and strain. 

Applications of Nichrome Wire

Heating elements: Hair dryers, toasters, and other machines needing high-temperature heating elements use nicchrome wire. 

Industrial furnaces: Metals and other materials are melted in industrial furnaces using nichrome wire. 

Laboratories: Heating coils and hot plates are examples of equipment in the laboratory that uses nichrome wire. 

Construction: Rope heaters and heating cables are two construction-related uses for nichrome wire. 

Specialized electronics: In specialist electronics, such glassblowing and ceramic sculpture, nichrome wire is utilized. 

There are many uses for nichrome wire, which is a dependable and adaptable material. It is the perfect material to use in heating elements and other applications where high temperatures are prevalent because of its low resistivity, high temperature resistance, and oxidation resistance. This guide provides all the information you need, whether you’re searching for a material for a particular application or you just want to learn more about Nichrome wire.

To Calculate
Gauge (dia)


  • RN = (Wire Length (inch) / 12) x RPF
  • Vp = I x RN
  • Power = I x Vp

where :

  • RPF = Resistance per Feet (Ohms)
  • I = Current Required (Amps)
  • Vp = Volts
