Product Description

Cr20Ni80 wire is made by nickel-chromium alloys in wire and ribbon (flat wire) form. More information about each type of resistance alloy and resistance heating alloy, such as chemical composition, is available in the datasheet for the respective grade.

Nikrothal NiCr nickel-chromium Nichrome resistance Heating Wire and Strip for use up to 1250ºC (2280ºF).

1. Size Range:

Round shape:

Diameter: 0.02mm-10mm for Cr20Ni80 wire.

Flat/Ribbon Shape:

thickness: 0.05mm-3mm; width: 0.1mm-150mm

2. Main Characteristics of Nichrome resistance Heating Heating Wire:

Relatively high resistance

Good oxidative stability surface.

High temperature class, and can maintain a high metal strength under high temperature.

It has good processing properties and weldability

Can be widely used in metallurgy industry, household appliances, etc.

3.Nichrome resistance Heating Wire Description:

Cr20Ni80 – Industrial furnaces (upto 1200°C), electric cooking equipment, precision resistors.

Cr30Ni70 – Industrial furnaces (upto 1230°C) with alternating oxidizing/reducing atmosphere, precision resistors.

Cr15Ni60 – Industrial furnaces (upto 1100°C), electrically heated equipment, high-resistance and potentiometer resistors.

All the materialwe use is selected from famous factory both home and abroad.

The quality of our products is strictly controlled as per our national standards, so we are always enjoying good reputations.

our electrical resistance ribbon/wire includes:

a) FeCrAl alloy ribbon/wire
0Cr25Al5,0Cr23Al5,0Cr21Al6,0Cr21Al4,0Cr21Al6,Kanthal A1, KanthalD0Cr19Al3,0Cr15Al5,0Cr13Al4,0Cr27Al7Mo2,etc.

The heating resistance of Iron-Chrome-Aluminum (Fe-Cr-Al) series metal alloy grows as the increment of the composition of Chrome and Aluminum.

It has superior anti-oxidization, anti-sulfur and anti-cementite.

It also has series of advantages as small density, high surface load, high resistivity, high service temperature, long life-span and low price etc.

b) Cr20Ni80 wire

Cr20Ni80,Cr15Ni60,Cr20Ni30,Cr20Ni35,Cr30Ni70,etc.The Nickel-Chrome,

Nickel-Chrome-Iron series metal alloy have a series of advantage such as good anti-oxygen, high strength, not soften etc.

No distortion and permanent elongations are very small while using with long hours.

Application of Cr20Ni80 wire:

Conductive wire -- Round and flat conductive wire (magnet wire) in aluminium, copper clad aluminium, and copper.

Resistance heating wire and resistance wire -- for a variety of heat generating and electronic applications.

Spray wire -- Thermal spraying wire in a wide range of alloys for high-temperature corrosion protection, bonding layers and sealing.

Thermocouple wire -- Wire and ribbon for thermocouples, extension leads and compensating cables.
