OhmAlloy112 is a nickel-chromium alloy (NiCr alloy) characterized
by high resistivity, good oxidation resistance ,good form stability
and good ductility and excellent weldability. It is suitable for
use at temperatures up to 1150°C.
Typical applications for OhmAlloy112 are used in metal sheathed
tubular elements,for example,hot plates,grills,toaster ovens and storage heaters.The alloys is also used
for suspended coils in air heaters in clothes dryers,fan
heaters,hand dryers etc.
