I search for Nichrome plate long time, and successfully bought it from Ohmalloy material. OHMALLOY provide real good service in alloy service and can always help me in finding the correct resistance alloy.

—— Mike Harness

OHMALLOY can provie me only 1kg Kovar alloy wire 1.0mm with short time, that is really amazing. Thanks

—— Janey

Really professional in thermocouple wire and cable, what i want just can get from OHMALLOY

—— Chris

Enamelled Constantan 0.08mm, i never expect to get only 2kg of it. But OHMALLOY supply it to me with good quality. God Jesus! Such a reliable supplier from china

 OhmAlloy49(Resistance heating wire and resistance wire)
(Common Name:CuNi44,NC50.Cuprothal, Alloy 294, Cuprothal 294, Nico, MWS-294, Cupron, Copel, Alloy 45, Neutrology, Advance, CuNi 102, Cu-Ni 44, Konstantan,constantan.)
 
    OhmAlloy49 is a copper-nickel alloy (Cu56Ni44 alloy) characterized by high electrical resistance, high ductility and good corrosion resistance. It is suitable for use at temperatures up to 400°C
Typical applications for OhmAlloy49 are temperature-stable potentiometers, industrial rheostats and electric motor starter resistances.
    The combination of negligible temperature coefficient and high resistivity makes the alloy particulary suitable for the winding of precision resistors.
OhmAlloy49 is manufactured from electrolytic copper and pure nickel. In finer wire sizes the alloy is designated as OhmAlloy49TC(Thermocouple).
