(Common Name: Ni80Cr20,Nikrothal 8,MWS-650,NiCrA,Tophet A,HAI-NiCr
80,Chromel A,Alloy A,Alloy 650,N8,Resistohm 80, Stablohm
650,Nichorme V,Nikrothal 80.)
OhmAlloy109 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 1200°C,and
hold a superior service life compared to Iron chromium alumium
alloys.
Typical applications for OhmAlloy109 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.
