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

OhmAlloy118
(Common Name:Ni70Cr30, Nikrothal 70, N7, HAI-NiCr 70, Chromel 70/30, Resistohm 70, Balco,Tophet 30,Cronix 70,Alloy 710,Stablohm 710)

 

OhmAlloy118 is a nickel-chromium alloy (NiCr alloy) characterized byHigh resistivity, good oxidation resistance,very good form stability,good ductility and excellent weldability. It is suitable for use at temperatures up to 1250°C.

Typical applications for OhmAlloy118 are used in electrical heating elements in industrial furnace,and well suited for reducing atmospheres.

Characteristics:

1) The highest working temperature up to 1250 degree.

2) Higher elongation

3) More stable mechanical properties

4) Better ductility and weldability.

Applications

Nichrome alloy resistance strip Ni70Cr30 is widely used for making electric heating elements in home appliances and industrial furnaces. Typical applications are flat irons, ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements and cartridge elements.
