Alloy 675,Nikrothal 6, MWS-675, Stablohm 675,NiCrC)
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.

What are the applications?
Resistance wires are manufactured from nickel alloys which have
specialist properties such as electrical resistance, oxidation
resistance, strength and corrosion resistance – all at elevated
temperatures.
Resistance wire is thus used primarily in resistance heating
elements, hot wire cutting, heat sealing, resistors and springs and
fasteners for high technology industries. It is also used
extensively as a glass sealing element.
