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.
