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

The addition of nickel to pure copper can significantly improve the strength, corrosion resistance, hardness, electrical resistance and thermoelectricity, and reduce the temperature coefficient of resistivity. Therefore, compared with other copper alloys, the mechanical and physical properties of cupronickel are extremely good, with good ductility, high hardness, beautiful color, corrosion resistance and deep drawing performance.


It is widely used as corrosion-resistant structural parts in shipbuilding, petroleum, chemical, construction, electric power, precision instruments, medical equipment, musical instruments and other departments. Some cupronickel has special electrical properties, which can be used to make resistance elements, thermocouple materials and compensation wires. Non-industrial cupronickel is mainly used to make decorative crafts.
