Ni70cr30 Belt for Double Strip Coils Braking Resistor
Ni70Cr30 is a nickel-chromium alloy (NiCr alloy) characterized by
high resistivity, good oxidation resistance and very good form
stability. It is suitable for use at temperatures up to 1250°C,and
hold a superior service life compared to Iron chromium alumium
alloys.
Typical applications for Ni70Cr30 are electric heating elements in
home appliances,industrial furnaces and resistors(wirewound
resistors,metal film resistors), flat irons, ironing machines,
water heaters, plastic moulding dies, soldering irons, metal
sheathed tubular elements and cartridge elements.
