Product Description

OhmAlloy109
(Common Name: Ni80Cr20,Nikrothal 8,MWS-650,NiCrA,Tophet A,HAI-NiCr 80,Chromel A,Alloy A,Alloy 650,N8,Resistohm 80, Stablohm 650,Nichorme V,Nikrothal 80.)

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.
