high temperature ni70cr30 cr20ni80 nicr nichrome resistance wire

Heat resistance wire is a type of high resistance electrical wire. The wire resists the flow of electricity, and converts the electrical energy into heat.

Nichrome, a non-magnetic alloy of nickel and chromium, is commonly used to make resistance wire because it has a high resistivity and resistance to oxidation at high temperatures. When used as a heating element, resistance wire is usually wound into coils.

The high nickel content, in combination with the high chromium content let the scaling temperature can reach to 1250ºC

Chrome Nickel wire was shaped by means of high speed automatic cooling machine of which the power capacity is controlled by computer, they are available as wire and ribbon(strip).

Uses of nichrome wire

Chrome nickel wire resistance is widely used for making electric heating elements in home appliances and industrial furnaces.,various electrical resistors and locomotive braking resistor, infrared equipment, liquefied gas infrared heat-resisting net, different kinds of igniting and radiating electrodes and voltage-regulating resistors for motors and so on in Metallurgical machinery

nichrome wire resistance Main characteristics

nichrome wire resistance Notice

Resistance electric heating wire has strong antioxidant properties, but a variety of gases in furnaces such as air, carbon, sulfur, hydrogen and nitrogen atmosphere, still have a certain impact on it.

Although these heating wires all have had antioxidant treatment, the transportation, winding, installation and other process will cause damage to a certain extent and reduce its service life.

In order to extend the service life, customers need to do pre oxidation treatment before using. The method is to heat alloy elements which have installed completely in the dry air to the temperature (lower 100-200C than its maximum using temperature), heat preservation for 5 to 10 hours, then cooling slowly with furnace.
