Good quality Bimetallic Strip for sales
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

Nichrome has a silvery gray coloration. Nichrome wires are quite oxidation resistant. When at a high temperature environment, up to 1200 C (Nicr 8020), both nickle oxide and chromium oxide will be formed. As chromium oxide is more stable than nickel oxide, a layer of chromium oxide will be formed on the surface of the nichrome wire. The diffusion rate D of oxygen through chromium oxide is very low, which is 10-14 cm2/sec.

 

In order to have enough resistance, mental conduct wires always are designed into thin form. They process of oxidation will be quick, making them brittle and break when heated in air. By contrast, not only does nichrome have a excellent oxidation resistant, it also has a good ductility after high temperature use. Besides that, nichrome alloys have a higher emissivity compared to other air-stable resistance alloys. Nichrome alloys will endure a lower element temperature at the same surface load. Moreover, Nichrome alloys will be preferred in low-temperature applications because of its non-magnetic feature. It also has a higher hot and creep strength, wet corrosion resistance and good wear resistance.

 

Typical applications for OhmAlloy109 are electric heating elements in home appliances,industrial furnaces and resistors(wirewound resistors,metal film resistors), flat irons, ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements and cartridge elements.
