OhmAlloy109
(Common Name:Ni80Cr20, Nikrothal8 ,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, very good form
stability after use and very good weldability. 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 appliance, industrial furnaces and resistors( wirewound resistors, metal
film resistors) such as flat irons, ironing machines, water heaters, plastic moulding dies,
soldering irons, metal sheathed tubular elements and cartridge
elements.
