Ni35cr20 Resistance Strip for Electric Heating Elements
1.Product Detail:
Ni35Cr20 is an alloy used at operating temperatures up to 1850 °F (1030°C). It is a non-magnetic alloy made from nickel,
chromium and iron that has a lower resistivity than Chromel C, but improved resistance to selective oxidation of chromium.

2.Applications
Industrial furnaces, metals melting, hair dryers, ceramic supports in incinerators
Nickel-chromium, nickel-chromium alloy with high and stable resistance, corrosion resistance, surface resistance to
oxidation is good, under high temperature and seismic strength better ductility,
better working capacity, and better welding.
Cr20Ni80: in braking resistors, industrial furnaces, flat irons, ironing machines, water heaters, plastic molds,
iron welders, coated tubular elements and cartridge elements.
Cr30Ni70: in industrial furnaces. Well suited for the reduction of atmospheres, since it is not subject to
the rottenness of the "green rot".
Cr15Ni60: in the braking resistors, industrial ovens, hot plates, grills, toaster ovens and storage heaters.
For coils suspended in air heaters and clothes dryer, fan heater, hand dryer.
Cr20Ni35: in braking resistors, industrial furnaces. In night-time heaters, high resistance rheostats and fan heaters.
For heating wires and rope heaters in de-icing elements, blankets and electric pads, cartridge seat,
base plate heaters and floor heaters.
Cr20Ni30: in solid hot plates, open coil heaters in HVAC systems, night storage heaters, convection heaters,
high resistance rheostats, and fan heater. For heating wires and rope heaters in de-icing elements,
blankets and electric pads, cartridge seat, base plate heaters, floor heaters and resistors.
