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

Shunt Manganin 43(Precision Resistance wire)
(Common Name: Manganin 43,CuMn12Ni4,Manganin )


Shunt Manganin 43 is a copper-manganese-nickel alloy (CuMnNi alloy) for use at room temperature. The alloy is characterized by very low thermal electromotive force (emf) compared to copper.


Shunt Manganin43 widely used for Shunt resistor with the highest requirements, shunt manganin43 has been used in precision built electrical components such as Wheatstone bridges, decade boxes, voltage drivers, potentiometers and resistance standards.
