Product Description

Product Description

nicr8020

Heating conductor alloys nichrome alloy round and flat wire 0.1*5mm

Definition:
Resistance wire is a type of wire that has a high electrical resistance, meaning it resists the flow of electric current.
It is typically made from alloys such as nichrome (nickel-chromium) or (iron-chromium-aluminum), which have specific electrical properties that make them suitable for applications where heat is generated.
Resistance wire is commonly used in heating elements, electrical appliances, industrial furnaces, and other devices that require controlled heating or temperature regulation.
Resistance wire is chosen for its ability to generate heat efficiently and withstand high temperatures without melting or deforming.

Grade: Ni80Cr20 ,MWS-650,NiCrA,Tophet A,HAI-NiCr 80,Chromel A,Alloy A,N8,Resistohm 80, Stablohm 650,Nichorme V etc.

Resistance wire is a type of wire made from a material with high electrical resistance, such as nichrome.
It is commonly used in heating elements, such as those found in toasters, ovens, and hair dryers, as well as in industrial applications like furnace heating and thermocouples.
The high resistance of the wire allows it to generate heat when an electric current is passed through it, making it an effective heating element.
